Three sisters spent a total of $57. Barbara spent $8 more than Linda and Eva spent $14 more than Barbara.
- How much money did Linda spend?
- How much money did Eva spend?
(a)
Amount that Linda spent = 1 u
Amount that Barbara spent = 1 u + 8
Amount that Eva spent = 1 u + 8 + 14 = 1 u + 22
Total amount that they spent
= 1 u + 1 u + 8 + 1 u + 22
= 3 u + 30
3 u + 30 = 57
3 u = 57 - 30
3 u = 27
1 u = 27 ÷ 3 = $9
Amount that Linda spent
= 1 u
= 9
(b)
Amount that Eva spent
= 1 u + 22
= 9 + 22
= $31
Answer(s): (a) $9; (b) $31
