Answer: The customer will make $80 as interest in 4 months.
Explanation:
Given: Deposited amount : P = $4000
Rate of interest per year : r= 6% =0.06
Rate of interest monthly =
![(r)/(12)=(0.06)/(12)=0.005](https://img.qammunity.org/2021/formulas/mathematics/high-school/9gyqd5r6hfoolhw408uzgmvok3vrhuncx2.png)
Time = 4 months
Simple interest = principal x rate of interest x time
![=4000* 0.005* 4=80](https://img.qammunity.org/2021/formulas/mathematics/high-school/dzj4fc9o14ulzya6hqlptob0pfps8j5klj.png)
hence, the customer will make $80 as interest in 4 months.
