Question 1

A total of 114 people signed up on the first day that a new fitness center opened in town.

Write the prime factorization of the

number of people who joined on the first day.

Question 2Nathan just got his driver’s license. On

Monday he drove 5.25 miles to school and 6.5 miles on the way home

because he takes his friend Harry home. His dad is going to let him drive

to school all week. Which equation can be used to find t, the total miles

Nathan will drive this week?

a. (6.5 - 5.25) x 5 = t b. 6.5 + 5.25 x 5 = t c. (6.5 + 5.25) x 5 = t d. (6.5 + 5.25) ÷ 5

= t

Question 3

Lynn went to the store to buy food for supper. She bought a pizza for $8.89, a salad mix for $2.39, and four soft drinks at $.79 each. What is the best estimate for the amount of money Lynn spent at the

42 + (15 + 13) 7

Go Aunt Sally!

Question 5

Joe’s father drives a truck 8 hours per day. On Monday, Wednesday

and Friday, he drives 45 miles each day. On Thursday and Tuesday, he

drives 30 miles each day. Which equation could be used to show t, the total miles driven in the 5-day

week?a. (45 + 30) x 5 = t b. (45 x 2) + (30 x 3) = tc. 45 + 30 x 3 x 2 = t d. (45 x 3) + (30 x 2) = t

Question 6Mr. Smith always buys plenty

of goodies at Halloween. Here is what he has bought:

Raisins 2.75 pounds $4.95
