Math - 5th graders Kara and Rani both have lemonade stands. Kara sells

5th graders Kara and Rani both have lemonade stands. Kara sells her lemonade at 5 cents a glass and Rani sells hers at 7 cents a glass. Kara sold 17 glasses of lemonade today and Rani sold 14 glasses. Who made the most money and by what amount? 
a. Kara, 13 cents 
b. Rani, 13 cents 
c. Kara, 85 cents 
d. Rani, 98 cents

Answer: b. Rani, 13 cents 

First, simplify the problem: K = 5 × 17 = 85, so Kara made 85 cents; R = 7 × 14 = 98, so Rani made 98 cents, so Rani made the most money; R − K = 98 − 85 = 13. Therefore, Rani made 13 cents more than Kara.
