Solutions

Question 1
To find the approximate number of homeschooling families, divide the total number of homeschool students by the average number of students per family: 2,983 / 3 = 994.33. Rounded to the nearest thousand, this is 994.

Question 2
To find the average number of visitors per day, we need to divide the total number of visitors by the number of days the park is open. 3333 divided by 5 is 666.6, which rounds to 667 (rounded to the nearest thousand, as specified in the question). Therefore, approximately 667 visitors come to the water park every day.

Question 3
To find the number of jars of cookies, divide the total number of cookies by the number of cookies in each jar: 3,795 ÷ 60 = 63. Therefore, Ms. Brown baked 63 jars of cookies.

Question 4
To find the number of toys sold each day, we divide the total number of toys sold by the number of days the store is open. 13,405 / 7 = 1,915 We need to round this number to the nearest thousand since the question asks us to do so. Rounding 1,915 to the nearest thousand, we get: 2,000 toys sold each day. Therefore, the answer is 2000.

Question 5
To find the approximate number of candies produced by each machine, divide the total number of candies produced by the number of machines: 3,800 / 8 = 475. So each machine can produce approximately 475 candies.

Question 6
To find the total number of fish fillets, we multiply the number ordered by the number of guests. 3 x 150 = 450. Therefore, about 450 fish fillets were ordered.

Question 7
To find the number of baskets left, we can subtract the number of baskets sold from the total number of baskets bought: 276 - 189 = 87. Therefore, Jill had 87 baskets left.

Question 8
To determine how many soccer balls John can purchase, divide his total money by the cost of each soccer ball: $150 ÷ $25 = 6. Therefore, John can purchase 6 soccer balls.

Question 9
To find the number of cupcakes left after the wedding, we need to subtract the number of cupcakes sold from the total number of cupcakes made. 4,567 - 3,213 = 1,354. Therefore, approximately 1,354 cupcakes were left after the wedding.

Question 10
To find the answer, multiply the number of pizzas the chef can make per day (2,820) by the number of days in a month (usually considered as 30): 2,820 x 30 = 84600. Since we are rounding to nearest thousand, the answer is 84000.

Question 11
To find the total number of baked goods, we simply add the number of cupcakes and cookies: 3,212 + 2,496 = 5,708. Therefore, the answer is 5708.

Question 12
To determine how many hours it takes to get to the destination, divide the total distance by the speed of the car: 350 miles ÷ 60 miles per hour = 5.8333... hours. Rounding to the nearest thousand, the answer is 6. Therefore, it will take approximately 6 hours to get to the destination.

Question 13
To find the number of boxes left, we can subtract the number of boxes shipped from the total number of boxes produced: 1,358 - 956 = 402. Therefore, there were 402 boxes left.

Question 14
To find the total number of meters completed by the athletes, we can multiply the length of each lap by the number of laps completed. 10 laps * 894 meters/lap = 8940 meters. Since we need to round to the nearest thousand, we get 9000 as our final answer.

Question 15
To find out how many tasks the machine can complete in 6 hours, we need to multiply the number of tasks it can complete in one hour (18) by the number of hours (6). This gives us 18 x 6 = 108. Therefore, the machine can complete approximately 108 tasks in 6 hours.

Question 16
To find out the number of stuffed animals produced in a week, we need to multiply the daily production by 7 (as there are 7 days in a week). So, 7,350 x 7 = 51,450. Since we need to round the answer to the nearest thousand, we get 51,000.

Question 17
To find the approximate number of dresses that each sewing machine can make, divide the total number of dresses made by the number of sewing machines: 1,200 / 4 = 300. So each sewing machine can make approximately 300 dresses.

Question 18
To find the number of classrooms needed, we divide the total number of students (90) by the number of students that can fit in each classroom (30). 90 ÷ 30 = 3 Therefore, the teacher needs 3 classrooms.

Question 19
To find the number of baskets left, we can subtract the number of baskets sold from the total number of baskets bought: 276 - 189 = 87. Therefore, Jill had 87 baskets left.

Question 20
To find out the total number of chicken nuggets ordered, we need to multiply the number of students by the number of chicken nuggets each student ordered. So, 120 students * 7 chicken nuggets per student = 840 chicken nuggets. Therefore, the answer is 840.
