Damon loaned Jennifer $300 at an annual interest rate of 6%. If no payments are made, what is the total amount owed at the end of the first year?
| $318 | |
| $315 | |
| $306 | |
| $303 |
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 $300
i = 0.06 x $300
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $300 + $18What is -6a2 x 2a3?
| -4a2 | |
| -12a5 | |
| -12a3 | |
| -4a5 |
To multiply terms with exponents, the base of both exponents must be the same. In this case they are so multiply the coefficients and add the exponents:
-6a2 x 2a3
(-6 x 2)a(2 + 3)
-12a5
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 35% off." If Bob buys two shirts, each with a regular price of $29, how much will he pay for both shirts?
| $47.85 | |
| $10.15 | |
| $18.85 | |
| $31.90 |
By buying two shirts, Bob will save $29 x \( \frac{35}{100} \) = \( \frac{$29 x 35}{100} \) = \( \frac{$1015}{100} \) = $10.15 on the second shirt.
So, his total cost will be
$29.00 + ($29.00 - $10.15)
$29.00 + $18.85
$47.85
What is \( \frac{3}{5} \) x \( \frac{1}{5} \)?
| \(\frac{3}{5}\) | |
| \(\frac{3}{25}\) | |
| \(\frac{1}{35}\) | |
| \(\frac{3}{32}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{5} \) x \( \frac{1}{5} \) = \( \frac{3 x 1}{5 x 5} \) = \( \frac{3}{25} \) = \(\frac{3}{25}\)
