I use a bit of a different looking formula.
A(t)=P(1+r/n)^nt
P=amount of money. (500)
r= rate (in decimal. 4%=0.04)
n=number of times per year (1 in this problem)
t=amount of time. (5 years)
Plugged in it looks like this:
A(t)=500 (1+ 0.04/1)^1x5
Then I put it into my calculator like this:
0.04/1+ 0.04
Then add one to the above answer:
0.04+1=1.04
Then raise the above answer to the 1x5:
1.04^5=1.2166......
Then multiply the above answer by 500:
1.2166.... x 500=608.3264512

Hope this helps, let me know if you have any questions.

Answer:
75 minutes
Step-by-step explanation:
Make an equation
4 pies to 15 minutes = 20 pies to x minutes
4 / 15 = 20 / x
Now cross multiply
4x = 15 × 20
And multiply 15 and 20
4x = 300
Then divide both sides by 4
x = 75
So your answer is 75 minutes
