How many 8-passenger vans will it take to drive all 71 members of the football team to an away game?
| 7 vans | |
| 9 vans | |
| 10 vans | |
| 6 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{71}{8} \) = 8\(\frac{7}{8}\)
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 5% off." If Roger buys two shirts, each with a regular price of $29, how much will he pay for both shirts?
| $30.45 | |
| $56.55 | |
| $1.45 | |
| $31.90 |
By buying two shirts, Roger will save $29 x \( \frac{5}{100} \) = \( \frac{$29 x 5}{100} \) = \( \frac{$145}{100} \) = $1.45 on the second shirt.
So, his total cost will be
$29.00 + ($29.00 - $1.45)
$29.00 + $27.55
$56.55
Christine scored 83% on her final exam. If each question was worth 3 points and there were 210 possible points on the exam, how many questions did Christine answer correctly?
| 58 | |
| 62 | |
| 45 | |
| 69 |
Christine scored 83% on the test meaning she earned 83% of the possible points on the test. There were 210 possible points on the test so she earned 210 x 0.83 = 174 points. Each question is worth 3 points so she got \( \frac{174}{3} \) = 58 questions right.

Alex loaned Christine $1,300 at an annual interest rate of 7%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,326 | |
| $1,378 | |
| $1,313 | |
| $1,391 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,300
i = 0.07 x $1,300
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,300 + $91
