Question 1.
A family of 2 adults and 2 children has $30.00 to spend on roller coaster rides. Do they also have enough money for each person to buy a Mexican grilled corn? Explain.

Answer:
Yes, they have enough money because total cost of to spend on roller coaster rides = $27.90 which is less than the amount they have to spend $30.

Explanation:
Cost of adult coaster ride = $7.75.
Cost of children coaster ride = $4.50.
Cost of each Mexican grilled corn = $0.85.
Number of adults in a family = 2.
Number of children in a family = 2.
Amount of money they have to spend = $30.
Cost of all coaster rides = (Cost of adult coaster ride × Number of adults in a family) + (Cost of children coaster ride × Number of children in a family)
= ($7.75 × 2) + ($4.50 × 2)
= $15.50 + $9.00
= $24.50.
Cost of four Mexican grilled corn = 4 × Cost of each Mexican grilled corn
= 4 × $0.85
= $3.40.
Total cost of to spend on roller coaster rides = Cost of all coaster rides + Cost of four Mexican grilled corn
= $24.50 + $3.40
= $27.90.

Number of can of tomatoes = 3.
Total weight of cans of tomatoes = Weight of each can of tomatoes × Number of can of tomatoes
= 1.75 × 3
= 5.25 pounds.
Difference:
Total weight of bottles of water – Total weight of cans of tomatoes
= 8.76 – 5.25
= 3.51 pounds.

Question 23.
The Ruiz family, 2 adults and 2 children, visit the science museum. The Brinker family, 1 adult and 3 children, visit the zoo. Each family has $60.00 to spend on admission. Which family will spend less on admission?

Answer:
The Brinker family will spend less on admission.

Explanation:
Cost of adult admission for visit the science museum = $15.00
Cost of children admission for visit the science museum = $10.00
Number of adults in Ruiz family for visit the science museum = 2.
Number of children in Ruiz family  for visit the science museum = 2.
Total cost for admission for visit the science museum of Ruiz family = (Cost of adult admission for visit the science museum × Cost of adult admission for visit the science museum) + (Number of children in Ruiz family  for visit the science museum × Cost of children admission for visit the science museum)
= (2 × $15) + (2 × $10)
= $30 + $20
= $50.
Cost of adult admission for visit the zoo = $13.50.
Cost of children admission for visit the zoo = $9.50.
Number of adults in Brinker family for visit the zoo = 1.
Number of children in Brinker family for visit the zoo = 3.
Total cost for admission for visit the zoo of Brinker family = (Cost of adult admission for visit the zoo × Number of adults in Brinker family for visit the zoo) + (Cost of children admission for visit the zoo × Number of children in Brinker family for visit the zoo)
= (1 × $13.50) + (2 × $9.50)
= $13.50 + $19.00
= $32.50.
Each family has $60.00 to spend on admission.
Comparison:
Total cost for admission for visit the science museum of Ruiz family = $50.
Total cost for admission for visit the zoo of Brinker family = $32.50.
Difference:
$60 – $50 = $10.
$60 – $32.50 = $27.50.
