The Formula for the compound interest is:

A = Amount Accumulated = $5000
P = Principal Amount = $1250
n = compound period in a year = 4
r = Interest Rate
t = Time in years = 12
Using the values in the formula, we get:

Thus, in order to achieve the given conditions, 11.72% interest rate is required.
-81=3(5-4r)
27=-(5-4r)
27=-5+4r
-4r=-5-27
-4r=-32
r=8
Hope my answer helped u :)
1/2 of 1/4 is 1/8 and 1/2 of 8 is 4 so 4 1/8 + 8 1/4 is 12 and 3/8 or about $12.38
