Roger loaned Latoya $900 at an annual interest rate of 3%. If no payments are made, what is the total amount owed at the end of the first year?
| $918 | |
| $927 | |
| $936 | |
| $963 |
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 $900
i = 0.03 x $900
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $900 + $27What is \( \frac{3}{9} \) x \( \frac{3}{8} \)?
| \(\frac{1}{7}\) | |
| \(\frac{2}{45}\) | |
| \(\frac{1}{8}\) | |
| \(\frac{1}{25}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{3}{9} \) x \( \frac{3}{8} \) = \( \frac{3 x 3}{9 x 8} \) = \( \frac{9}{72} \) = \(\frac{1}{8}\)
