How many levels are in the game? You would take that number and multiply it by 0.72 to find 72% of it.
Please enclose the "nt" inside parentheses: <span>A(t)=P(1+r/n)^(nt).
Then: A = $500*(1+0.06/12)^(5*12) = $641.68</span>
10^5 is equivalent to 100,000. I hope this answers your question and I hope you have a great day ! :)
