## anonymous one year ago 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

for the second one, multiply the first one by $$.5$$ to get $.5\times 10(1.2)^n$
