Bob loaned April $600 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?
| $630 | |
| $642 | |
| $636 | |
| $612 |
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 $600
i = 0.07 x $600
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $600 + $42
