You can use A=P(1+(r/n))^(nt)
n=homany times it is compounded a year: 1 annually
t=time in years
r=rate: 6% or .06
A=Final Amount
P=principle amount
A=1000(1+(.06/1))^(1*t)
8 + _ = 10
10 - 8 = 2
8 + 2 = 10
You end with 210.85. add 75.50 and 55.25 together you get 130.75. 130.75-25.15-18.65 = 86.95. 210.85-86.95= 123.90 work backwards.
