Three sisters spent a total of $95. Jean spent $12 more than Cindy and Irene spent $8 more than Jean.
- How much money did Cindy spend?
- How much money did Irene spend?
(a)
Amount that Cindy spent = 1 u
Amount that Jean spent = 1 u + 12
Amount that Irene spent = 1 u + 12 + 8 = 1 u + 20
Total amount that they spent
= 1 u + 1 u + 12 + 1 u + 20
= 3 u + 32
3 u + 32 = 95
3 u = 95 - 32
3 u = 63
1 u = 63 ÷ 3 = $21
Amount that Cindy spent
= 1 u
= 21
(b)
Amount that Irene spent
= 1 u + 20
= 21 + 20
= $41
Answer(s): (a) $21; (b) $41
