A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 35% off." If Roger buys two shirts, each with a regular price of $26, how much will he pay for both shirts?
| $33.80 | |
| $39.00 | |
| $42.90 | |
| $16.90 |
By buying two shirts, Roger will save $26 x \( \frac{35}{100} \) = \( \frac{$26 x 35}{100} \) = \( \frac{$910}{100} \) = $9.10 on the second shirt.
So, his total cost will be
$26.00 + ($26.00 - $9.10)
$26.00 + $16.90
$42.90

The greatest common factor (GCF) is the greatest factor that divides two integers.
What is \( \frac{24\sqrt{8}}{8\sqrt{2}} \)?
| \(\frac{1}{3}\) \( \sqrt{\frac{1}{4}} \) | |
| \(\frac{1}{4}\) \( \sqrt{3} \) | |
| 3 \( \sqrt{4} \) | |
| \(\frac{1}{4}\) \( \sqrt{\frac{1}{3}} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{24\sqrt{8}}{8\sqrt{2}} \)
\( \frac{24}{8} \) \( \sqrt{\frac{8}{2}} \)
3 \( \sqrt{4} \)
Damon loaned Diane $800 at an annual interest rate of 1%. If no payments are made, what is the total amount owed at the end of the first year?
| $872 | |
| $808 | |
| $856 | |
| $840 |
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 $800
i = 0.01 x $800
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $800 + $8If a car travels 120 miles in 8 hours, what is the average speed?
| 65 mph | |
| 50 mph | |
| 25 mph | |
| 15 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)
