so,
= v v=6
Each student gave 6 dollars. This is true due to the fact that
=6
28X6=128
20.15625 is the answer to your question if you would like the method you move the percentage two decimal places and multiply.
Present value, P = 20
compounding interest per 6 months, i = 0.025/2 = 0.0125
Number of periods, n = 30*2 = 60 (half-years)
Future value in 30 years
=P(1+i)^n
=20(1.0125)^60
= $42.14
