Question

Andre has 4 times as many model cars as Peter, and Peter has one-third as many model cars as Jade. Andre has 36 model cars. Write and solve an equation to find how many model cars Peter has. Using your answer from part a, write and solve an equation to find how many model car Jade has.

Answer 1

1) Name the variables:

A: number of model cars Andre has

P: number of model cars Peter has

J: number of model cars Jade has.

2) Statements:

Andre has 4 times as many model cars as Peter: A = 4 P

Peter has one-third as many model cars as Jade: P = J / 3

Andre has 36 model cars: A = 36

3) Write and solve an equation to find how many model cars Peter has.

A = 4P => A/4 = P

=> P = A / 4

=> P = 36 / 4 = 8

4) Using your answer from part a, write and solve an equation to find how many model cars Jade has.

P = J / 3 => J = 3P

=> J = 3 (8) = 24
