The number 5 is repeated 3 times.
So, the mode is 5.

Question 4.
What is the median for this set of numbers?
3, 7, 2, 8, 9, 4, 6
Answer:
Given data 3, 7, 2, 8, 9, 4, 6
Set the numbers in the ascending or descending order.
2, 3, 4, 6, 7, 8, 9
The Median is the middle number.
Here 6 is in the middle.
So, the median is 6.

Question 5.
What is the range for this set of numbers?
2, 4, 9, 34, 35, 42, 15, 14
Answer:
Given data is 2, 4, 9, 34, 35, 42, 15, 14
Low number = 2
Highest number = 42
Range = 42 – 2
Range = 40
So, the range of the numbers is 40.

Question 6.
What is the mean for this set of numbers?
10, 20, 30, 69, 79, 89, 3
Answer:
Given data is 10, 20, 30, 69, 79, 89, 3
Mean = sum of observations/number of observations
Mean = (10 + 20 + 30 + 69 + 79 + 89 + 3)/7
Mean = 42.8
So, the mean of the set of numbers is 42.8

Question 7.
George earns tips of $10 for Sunday, $15 for Monday, and $35 for Tuesday. What is the average of his tips for the three days?
Answer:
Given data,
George earns tips of $10 for Sunday, $15 for Monday, and $35 for Tuesday.
Average = (10 + 15 + 35)/3
Average = 60/3
Average = 20
Therefore the average of his tips for the three days is $20.

Question 8.
If a group of 20 students in a class has an average age of 13 years, what would happen to the average if a student who was 12 years old was replaced with a student who was 14 years old?
Answer:
The average age of 20 students is 13.
sum/20 = 13
sum = 13 × 20
sum = 260
average = (12 + 14)/2 = 13
If 12 years old was replaced with a student who was 14 years old
average = (14 + 14)/2 = 14
So, the average becomes 14.

McGraw Hill Math Grade 8 Lesson 6.9 Answer Key Simple and Compound Interest

Practice the questions of McGraw Hill Math Grade 8 Answer Key PDF Lesson 6.9 Simple and Compound Interest to secure good marks & knowledge in the exams.

McGraw-Hill Math Grade 8 Answer Key Lesson 6.9 Simple and Compound Interest

Exercises Calculate

Question 1.
How much interest would you earn if you put $500 in a bank for 15 years and received simple interest of 8%?
Answer:
$ 600.00,

Explanation:
Simple Interest SI = \(\frac{P X R X T}{100}\),
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
Amount = Principle + Simple Interest,
SI = Amount – Principle,
P= $500,
R = 8%,
T = 15 yrs,
Simple Interest SI = \(\frac{P X R X T}{100}\),
= \(\frac{500 X 8 X 15}{100}\),
= 5 X 8 X 15,
= 600.

Question 2.
Calculate the simple interest on a bank account where you deposit $500 and earn 12% a year for 5 years.
Answer:
$300.00,

Explanation:
Simple Interest SI = \(\frac{P X R X T}{100}\),
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
Amount = Principle + Simple Interest,
SI = Amount – Principle,
P= $500,
R = 12%,
T = 5 yrs,
Simple Interest SI = \(\frac{P X R X T}{100}\),
= \(\frac{500 X 12 X 5}{100}\),
= 5 X 12 X 5,
= 300.

Question 3.
Calculate the ending balance of your savings account if you deposit $400 and earn simple interest of 7% for 5 years.
Answer:
$540.0,

Explanation:
Simple Interest SI = \(\frac{P X R X T}{100}\),
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years)
Amount = Principle + Simple Interest,
SI = Amount – Principle,
P= $400,
R = 7%,
T = 5 yrs,
Simple Interest SI = \(\frac{P X R X T}{100}\),
= \(\frac{400 X 7 X 5}{100}\),
= 4 X 7 X 5,
= 140
the ending balance = Principle + Interest,
A = 400 + 140 = 540.

Question 4.
Calculate the ending balance of your savings account if you deposited $1,000 and earned simple interest of 6% for 6 years.
Answer:
$1,360.00,

Explanation:
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
Amount = Principle + Simple Interest,
SI = Amount – Principle,
P= $1,000,
R = 6%,
T = 6 yrs,
Simple Interest SI = \(\frac{P X T X R}{100}\),
= \(\frac{1000 X 6 X 6}{100}\),
= 10 X 6 X 6,
= 360, The ending balance = Principle + Interest
A = $1,000 + $360 = $1,360.

Exercises Calculate

Question 5.
Calculate the interest earned over a 5-year period when you deposit $2,000 and earn compound interest of 8% per year.
Answer:
$938.66

Explanation:
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ]
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
P= $1,000,
R = 8%,
n = 5 yrs,
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
CI = 2000 [ 1 + \(\frac{8}{100}\)]5 – 1 ],
=2000 \(\frac{108}{100}\)5 – 1 ],
= 2000 X 0.469,
= $938.66.

Question 6.
How much interest would you earn if you put $500 in a bank for 20 years and received a compound interest rate of 4%?
Answer:
$595.56,

Explanation:
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
P= $500,
R = 4%,
n = 20 yrs,
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
CI = 500 [ 1 + \(\frac{4}{100}\)]20 – 1 ],
=500 \(\frac{108}{100}\)5 – 1 ],
= 500 [ 2.19 – 1],
= 500 x 1.19,
= $595.56.

Question 7.
How much money would you owe if you borrowed $2,000 for 5 years, with a compound interest rate of 28%, and did not make any payments during that period?
Answer:
$6871.95,

Explanation:
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
P = Principle Amount,
R =  Rate of interest in %,
T = Time (Number of years),
P= $2,000,
R = 28%,
n = 5 yrs,
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
CI = 2000 [ 1 + \(\frac{28}{100}\)]5 – 1 ],
=2000 \(\frac{128}{100}\)5 – 1 ],
= 2000 X 3.435,
= $6871.95.

Question 8.
Is it better to receive compounded interest for 7 years at 12% on your balance of $500, or to receive the same rate of simple interest for 9 years on that same balance?
Answer:
7 years at 12%, Balance, Compound interest $1105.34
Simple interest $140.00,

Explanation:
Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ],
P= $500, R = 12%, n = 7 yrs, Compound Interest CI = P [ 1 + \(\frac{R}{100}\) ]n – 1 ], CI = 500 [ 1 + \(\frac{12}{100}\)]7 – 1 ],
= 500 \(\frac{112}{100}\)7 – 1 ] = 500[2.210 – 1] = 500 x 1.210,
= $605.34. The ending balance = Principle + Compound interest,
A = $500 + $605.34 = $1,105.34,
Amount = Principle + Simple Interest,
SI = Amount – Principle, P= $500, R = 12%,
T = 9 yrs,
Simple Interest SI = \(\frac{P X R X T}{100}\),
= \(\frac{500 X 12 X 9}{100}\) = 5 x 12 x 9 = 540.00,
The ending balance = Principle + Simple Interest,
A = $500 + $540 = $1,040.00.
