Question

Wayne has a total of 100 Major League Baseball cards from both the American League and the National League. The number of American League cards is 10 more than twice the number of National League cards. Which system of equations can be used to find how many American Leagues cards, A, and National League cards, N, Wayne has?

Answer 1

A = 70 and N=30

Explanation:

Total - 100 cards

American League = A

National League = N

A = 2N + 10 and A+N = 100

100-10 = 90

90/3 = 30

A = 2(30) + 10 = 70

A = 70 and N=30
