Question

Tom and Jerry each have a Pokemon card collection.

-The number of cards in Tom’s collection can be represented by x.

-Jerry has quadruple the number of cards that Tom does.

If they have a total of 180 cards, how many does Jerry have?

Answer 1

T=x

J=4T = 4x

T+J=180

x+4x =5x = 180

x=180/5 =36

J=4x = 4(36)= 144= Jerry's number of cards
