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

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
