How many 10-passenger vans will it take to drive all 83 members of the football team to an away game?
| 3 vans | |
| 5 vans | |
| 10 vans | |
| 9 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{83}{10} \) = 8\(\frac{3}{10}\)
So, it will take 8 full vans and one partially full van to transport the entire team making a total of 9 vans.
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 30% off." If Charlie buys two shirts, each with a regular price of $12, how much money will he save?
| 57 | |
| $3.00 | |
| $0.60 | |
| $3.60 |
By buying two shirts, Charlie will save $12 x \( \frac{30}{100} \) = \( \frac{$12 x 30}{100} \) = \( \frac{$360}{100} \) = $3.60 on the second shirt.
What is the distance in miles of a trip that takes 4 hours at an average speed of 35 miles per hour?
| 140 miles | |
| 240 miles | |
| 270 miles | |
| 360 miles |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 35mph \times 4h \)
140 miles

A sports card collection contains football, baseball, and basketball cards. If the ratio of football to baseball cards is 3 to 2 and the ratio of baseball to basketball cards is 3 to 1, what is the ratio of football to basketball cards?
| 9:2 | |
| 9:4 | |
| 3:8 | |
| 3:2 |
The ratio of football cards to baseball cards is 3:2 and the ratio of baseball cards to basketball cards is 3:1. To solve this problem, we need the baseball card side of each ratio to be equal so we need to rewrite the ratios in terms of a common number of baseball cards. (Think of this like finding the common denominator when adding fractions.) The ratio of football to baseball cards can also be written as 9:6 and the ratio of baseball cards to basketball cards as 6:2. So, the ratio of football cards to basketball cards is football:baseball, baseball:basketball or 9:6, 6:2 which reduces to 9:2.
