Write a number sentence to help you solve each problem.
Two booths gave away free bottles of water to visitors on the first two days of the summer fair.

Question 27.
About how many bottles of water were given away on the first day? On the second day?
Answer:
Total number of bottles of water were given away on the first day = 181.
Total number of bottles of water were given away on the second day = 246.

Explanation:
Number of bottles of water were given away on the first day Booth 1 = 86.
Number of bottles of water were given away on the first day Booth 2 = 95.
Number of bottles of water were given away on the Second day Booth 1 = 117.
Number of bottles of water were given away on the Second day Booth 2 = 129.
Total number of bottles of water were given away on the first day = Number of bottles of water were given away on the first day Booth 1 + Number of bottles of water were given away on the first day Booth 2
= 86 + 95
= 181.
Total number of bottles of water were given away on the second day = Number of bottles of water were given away on the Second day Booth 1 + Number of bottles of water were given away on the Second day Booth 2
= 117 + 129
= 246.

Question 28.
Booth 2 had 144 bottles of water in the morning of the second day. How many bottles of water were left at the end of the day?
Answer:
The number of bottles of water left at the end of the day = 102.

Explanation:
Total number of bottles of water that were given away on the second day = 246.
Number of bottles of water in the morning on the second day = 144.
Number of bottles of water were left at the end of the day = Total number of bottles of water were given away on the second day – Number of bottles of water in the morning on the second day
= 246 – 144
= 102.

Question 29.
Which booth gave away more bottles of water in the two days?
Answer:
Booth 2 gave 21 more bottles of water in the two days.

Explanation:
Number of bottles of water were given away on the first day Booth 1 = 86.
Number of bottles of water were given away on the first day Booth 2 = 95.
Number of bottles of water were given away on the Second day Booth 1 = 117.
Number of bottles of water were given away on the Second day Booth 2 = 129.
Total number of bottles of water were given away Booth 1 = Number of bottles of water were given away on the first day Booth 1 + Number of bottles of water were given away on the Second day Booth 1
= 86 + 117
= 203.
Total number of bottles of water were given away Booth 2 = Number of bottles of water were given away on the first day Booth 2 + Number of bottles of water were given away on the Second day Booth 2
= 95 + 129
= 224.
Difference:
Total number of bottles of water were given away Booth 2 – Total number of bottles of water were given away Booth 1
= 224 – 203
= 21.

Question 30.
The fair has 77 booths. If Yuki and her friends went to 38 of the booths, how many booths did they miss?
Answer:
Number of booths they missed = 39.

Explanation:
Number of booths the fair has = 77.
Number of booths Yuki and her friends went = 38.
Number of booths they missed = Number of booths the fair has – Number of booths Yuki and her friends went
= 77 – 38
= 39.

Question 31.
The booths are in rows. Row A has 21 booths. Row B has 28 booths. How many booths are in Rows A and B?
Answer:
Number of booths in rows A and B = 49.

Explanation:
Number of booths in row A = 21.
Number of booths in row B = 28.
Number of booths in rows A and B = Number of booths in row A + Number of booths in row B
= 21 + 28
= 49.

Question 32.
Last year, 847 people attended the fair. This year, 921 people attended. How many more people attended this year?
Answer:
74 more people attended this year.

Explanation:
Number of people attended the fair Last year = 847.
Number of people attended the fair this year = 921.
Difference:
Number of people attended the fair this year – Number of people attended the fair Last year
= 921 – 847
= 74.

Write a number sentence to solve each problem
Question 1.
Last week 57 people visited the animal shelter. This week 64 people visited. How many people visited the animal shelter in the last two weeks?
57 + 64 = ?
57 + 54 = 121 people
Answer:
Number of people visited the animal shelter in the last two weeks = 121.

Explanation:
Number of people visited the animal shelter last week = 57.
Number of people visited the animal shelter this week = 64.
Number of people visited the animal shelter in the last two weeks = Number of people visited the animal shelter last week + Number of people visited the animal shelter this week
= 57 + 64
= 121.

Question 2.
This week the animal shelter spent $350 on dog food and $160 on cat food. How much more did the shelter spend on dog food than cat food this week?
Answer:
$190 more the shelter spend on dog food than cat food this week.

Explanation:
Amount of money this week the animal shelter spent on dog food = $350.
Amount of money this week the animal shelter spent on cat food = $160.
Difference:
Amount of money this week the animal shelter spent on dog food – Amount of money this week the animal shelter spent on cat food
= $350 – $160
= $190.

Question 3.
Last year the animal shelter took in 17 white cats. This year the animal shelter took in 12 white cats. How many more white cats did the shelter take in last year than it did this year?
Answer:
5 more white cats the shelter take in last year than it did this year.

Explanation:
Number of white cats Last year the animal shelter took = 17.
Number of white cats this year the animal shelter took = 12.
Difference:
Number of white cats Last year the animal shelter took – Number of white cats this year the animal shelter took
= 17 – 12
= 5.

Question 4.
On Saturday, volunteers collected $549 for the animal shelter. On Sunday, they collected $368. How much money did the volunteers collect last weekend?
Answer:
Amount collected by volunteers for the animal shelter last weekend = $917.

Explanation:
Amount collected by volunteers for the animal shelter on Saturday = $549.
Amount collected by volunteers for the animal shelter on Sunday = $368.
Amount collected by volunteers for the animal shelter last weekend = Amount collected by volunteers for the animal shelter on Saturday + Amount collected by volunteers for the animal shelter on Sunday
= $549 + $368
= $917.
