Karin is as old as her two cousins combined. If Karin is 54 and one cousin is 21, how old is the second cousin?

A. 13

B. 22

C. 33

D. 37

C. Create an equation to solve this problem.

Karin = cousin 1 + cousin 2.

You are told that Karin is 54 and one cousin is 21. Substitute that information into the formula.

54 = 21 + cousin 2

Solve for cousin 2 by subtracting 21 from both sides.

33 = cousin 2
