Answer:
Amount which is earned from bank B will be $7444.21
Explanation:
We have given principal amount P = $7500
Rate of interest r = 9 %
We have to find the interest after 8 years
Total amount after 8 year is given by
[tex]A=P(1+\frac{r}{100})^n=7500\times (1+\frac{9}{100})^8=7500\times 1.99256=$14944.21[/tex]
So the amount which he earn more = $14944.21 - $7500 = $7444.21
