Wesley, Sam and Ivan went shopping. Wesley and Sam spent a total of $260. Wesley and Ivan spent $656 altogether. Ivan spent 5 times as much as Sam.
- How much did Sam spend?
- How much did Wesley spend?
(a)
Amount that Wesley spent = W
Amount that Sam spent = S
Amount that Ivan spent = I
W + I = 656
W + S = 260
S = 1 u
I = 5 x 1 u = 5 u
Amount that Ivan spent more than Sam
= 5 u - 1 u
= 4 u
4 u = 656 - 260
4 u = 396
1 u = 396 ÷ 4 = 99
Amount that Sam spent
= 1 u
= $99
(b)
Amount that Wesley spent
= 260 - 99
= $161
Answer(s): (a) $99; (b) $161
