Answer: Edwin's deposit will earn an interest of $1327.50
We determine the simple interest on an amount deposited with the following formula:
![SI = P*N*R](https://img.qammunity.org/2019/formulas/business/middle-school/89t2romho3nuj49qtvvwwlqzwin32n8d0d.png)
where
SI = Simple Interest
P = Principal or the amount deposited
N = Number of years for which the deposit is made
R = annual rate of interest on the principal
Substituting the values from the question in the formula above we get,
![SI = 7500 * 3 * 0.059](https://img.qammunity.org/2019/formulas/business/middle-school/4noaqa9gpxmy38sqx4fy3oqsq04slsitja.png)
