Three brothers spent a total of $85. Barbara spent $8 more than Usha and Elyse spent $12 more than Barbara.
- How much money did Usha spend?
- How much money did Elyse spend?
(a)
Amount that Usha spent = 1 u
Amount that Barbara spent = 1 u + 8
Amount that Elyse spent = 1 u + 8 + 12 = 1 u + 20
Total amount that they spent
= 1 u + 1 u + 8 + 1 u + 20
= 3 u + 28
3 u + 28 = 85
3 u = 85 - 28
3 u = 57
1 u = 57 ÷ 3 = $19
Amount that Usha spent
= 1 u
= 19
(b)
Amount that Elyse spent
= 1 u + 20
= 19 + 20
= $39
Answer(s): (a) $19; (b) $39
