Heres the problem I was working on

I was trying to use the formula

P = (P/A),i,n)

but its not coming out to the correct answer of 324.71

Try this: A = 60 + 60(1.10)^(-1) + 60(1.10)^(-2) + 60(1.10)^(-3) + 60(1.10)^(-4) + 120(1.10)^(-5)

I tired that method but it doesnt work out to the correct answer.

sorry it did work, thanks.
