Damon loaned Monica $1,500 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?
| $1,575 | |
| $1,560 | |
| $1,605 | |
| $1,620 |
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 $1,500
i = 0.07 x $1,500
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,500 + $105A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 15% off." If Charlie buys two shirts, each with a regular price of $31, how much will he pay for both shirts?
| $44.95 | |
| $4.65 | |
| $32.55 | |
| $57.35 |
By buying two shirts, Charlie will save $31 x \( \frac{15}{100} \) = \( \frac{$31 x 15}{100} \) = \( \frac{$465}{100} \) = $4.65 on the second shirt.
So, his total cost will be
$31.00 + ($31.00 - $4.65)
$31.00 + $26.35
$57.35
How many 2 gallon cans worth of fuel would you need to pour into an empty 12 gallon tank to fill it exactly halfway?
| 6 | |
| 3 | |
| 9 | |
| 3 |
To fill a 12 gallon tank exactly halfway you'll need 6 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{6 \text{ gallons}}{2 \text{ gallons}} \) = 3

How many 8-passenger vans will it take to drive all 65 members of the football team to an away game?
| 9 vans | |
| 4 vans | |
| 11 vans | |
| 7 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{65}{8} \) = 8\(\frac{1}{8}\)
So, it will take 8 full vans and one partially full van to transport the entire team making a total of 9 vans.
