Answer 1

The interest after 7 months is $312.81

Step-by-step explanation:

Amount invested = $4875

rate = 11%

time = 7 months = 7/12 year

To get the interest, we will apply simple interest formula:

`\begin{gathered} I\text{ = PRT} \\ \text{where I = innterest} \\ P\text{ = principal = 4875} \\ R\text{ = 11\% = 0.11} \\ T\text{ = time = 7/12 } \end{gathered}`

Subtitute the values into the formula:

`\begin{gathered} I\text{ = 4875 }*0.11\text{ }*\text{ }(7)/(12) \\ I\text{ = 312.81} \end{gathered}`

The interest after 7 months is $312.81
