Carl, Xavier and Valen went shopping. Carl and Xavier spent a total of $293. Carl and Valen spent $679 altogether. Valen spent 3 times as much as Xavier.
- How much did Xavier spend?
- How much did Carl spend?
(a)
Amount that Carl spent = C
Amount that Xavier spent = X
Amount that Valen spent = V
C + V = 679
C + X = 293
X = 1 u
V = 3 x 1 u = 3 u
Amount that Valen spent more than Xavier
= 3 u - 1 u
= 2 u
2 u = 679 - 293
2 u = 386
1 u = 386 ÷ 2 = 193
Amount that Xavier spent
= 1 u
= $193
(b)
Amount that Carl spent
= 293 - 193
= $100
Answer(s): (a) $193; (b) $100
