Michael, Jenson and Perry went shopping. Michael and Jenson spent a total of $230. Michael and Perry spent $635 altogether. Perry spent 4 times as much as Jenson.
- How much did Jenson spend?
- How much did Michael spend?
(a)
Amount that Michael spent = M
Amount that Jenson spent = J
Amount that Perry spent = P
M + P = 635
M + J = 230
J = 1 u
P = 4 x 1 u = 4 u
Amount that Perry spent more than Jenson
= 4 u - 1 u
= 3 u
3 u = 635 - 230
3 u = 405
1 u = 405 ÷ 3 = 135
Amount that Jenson spent
= 1 u
= $135
(b)
Amount that Michael spent
= 230 - 135
= $95
Answer(s): (a) $135; (b) $95
