Roger loaned Latoya $200 at an annual interest rate of 2%. If no payments are made, what is the total amount owed at the end of the first year?
| $216 | |
| $204 | |
| $208 | |
| $206 |
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 $200
i = 0.02 x $200
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $200 + $4A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 40% off." If Roger buys two shirts, each with a regular price of $29, how much money will he save?
| $4.35 | |
| $11.60 | |
| $1.45 | |
| $5.80 |
By buying two shirts, Roger will save $29 x \( \frac{40}{100} \) = \( \frac{$29 x 40}{100} \) = \( \frac{$1160}{100} \) = $11.60 on the second shirt.

What is \( \frac{2}{7} \) x \( \frac{3}{7} \)?
| \(\frac{6}{49}\) | |
| \(\frac{2}{9}\) | |
| \(\frac{1}{16}\) | |
| \(\frac{12}{35}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{2}{7} \) x \( \frac{3}{7} \) = \( \frac{2 x 3}{7 x 7} \) = \( \frac{6}{49} \) = \(\frac{6}{49}\)
What is (x3)4?

| x-1 | |
| x12 | |
| x7 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
