Bob loaned Alex $700 at an annual interest rate of 7%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $49 | |
| $28 | |
| $30 | |
| $35 |
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 $700
i = 0.07 x $700
i = $49
