Answer:

She deposited $7500. So it is the principal.

At the end of  years, she had total of $8700.

So the total amount is $8700 and the time period is 2 years.

Interest = Total amount - principal = $8700 - $7500 = $1200

We need the rate of interest.

we know that Interest = PTR/100

⇒1200 = 7500*2*R/100

⇒R = 1200*100/7500*2

⇒R = 120000/15000 = 8%

Rate of interest is 8%

All you need to do for this is remove the parenthese and your answer will be \frac{H}{6} -1 because that's the furthest it can be simplified.
