-----------
Formula:
Future Value of an annuity:
S=R[(1+i)^n-1]/i
S=30[(1+0.05/12)^(12*19)]/[0.05/12]
S=30[2.580611313]/[0.004]
S=30*619.3467
S=$18580.40

If I have the right formula, this is my solution
FVA+=+A%2A%28%281+%2B+r%29%5En+-+1%29+%2F+r
FVA = future value of annuity
A = value of payments made each period
r = interest rate compounded for each period
n = number of payment periods
FVA+=+30%2A%28%281+%2B+.05%29%5E%2819%2A12%29+-+1%29+%2F+.05
FVA+=+30%2A%28%281.05%29%5E%28228%29+-+1%29+%2F+.05
log%28FVA%29+=+log%2830%29+%2B+228%2Alog%281.05%29+-%28log%285%29+%2B+log%2810%5E2%29%29
log%28FVA%29+=+1.477+%2B+228%2A.0212+-+2.699
log%28FVA%29+=+1.477+%2B+4.831+-+2.699
log%28FVA%29+=+3.609
FVA+=+10%5E3.609
FVA+=+4064.43
The amount of the annuity when their daughter
turns 19 is $4064.43
