compound-interest formula:
v = p( 1 + (r/n) )^(nt)
where:
v = final value
p = initial (principal) value
r = interest rate (as a decimal)
n = number of compounding periods per year
t = number of years
---
interest from 5.2%:
v = 2000*( 1 + (0.052/4) )^(4*2)
v = 2217.71
i = 2217.71 - 2000
i = 217.71
---
interest from 4.8%:
v = 2000*( 1 + (0.048/12) )^(12*2)
v = 2201.10
i = 2201.10 - 2000
i = 201.10
---
answer:
d = 217.71 - 201.10
d = 16.61
