Question

Sue set up a lemonade stand and sold 10 glasses of lemonade in the first hour. Her sales increased at the rate of 20% per hour for the next n hours. Which function represents the total number of glasses she sold in the nth hour? If the price of 1 glass of lemonade is $0.50, how much money did she earn in the nth hour?

The function that gives the total number of glasses sold in the nth hour is
a.f(n)=10x1.2^n
b.f(n)=10-1.2^n
c.f(n)=10+1.2^n
and the money she earned in the nth hour is
a.10x1.2^n
b.0.5(10x1.2^n)
c.10x2^n
