Three sisters spent a total of $95. Kylie spent $11 more than Emily and Sarah spent $13 more than Kylie.
- How much money did Emily spend?
- How much money did Sarah spend?
(a)
Amount that Emily spent = 1 u
Amount that Kylie spent = 1 u + 11
Amount that Sarah spent = 1 u + 11 + 13 = 1 u + 24
Total amount that they spent
= 1 u + 1 u + 11 + 1 u + 24
= 3 u + 35
3 u + 35 = 95
3 u = 95 - 35
3 u = 60
1 u = 60 ÷ 3 = $20
Amount that Emily spent
= 1 u
= 20
(b)
Amount that Sarah spent
= 1 u + 24
= 20 + 24
= $44
Answer(s): (a) $20; (b) $44
