Three sisters spent a total of $63. Min spent $10 more than Roshel and Eva spent $13 more than Min.
- How much money did Roshel spend?
- How much money did Eva spend?
(a)
Amount that Roshel spent = 1 u
Amount that Min spent = 1 u + 10
Amount that Eva spent = 1 u + 10 + 13 = 1 u + 23
Total amount that they spent
= 1 u + 1 u + 10 + 1 u + 23
= 3 u + 33
3 u + 33 = 63
3 u = 63 - 33
3 u = 30
1 u = 30 ÷ 3 = $10
Amount that Roshel spent
= 1 u
= 10
(b)
Amount that Eva spent
= 1 u + 23
= 10 + 23
= $33
Answer(s): (a) $10; (b) $33
