Three classmates spent a total of $75. Elyse spent $12 more than Usha and Linda spent $6 more than Elyse.
- How much money did Usha spend?
- How much money did Linda spend?
(a)
Amount that Usha spent = 1 u
Amount that Elyse spent = 1 u + 12
Amount that Linda spent = 1 u + 12 + 6 = 1 u + 18
Total amount that they spent
= 1 u + 1 u + 12 + 1 u + 18
= 3 u + 30
3 u + 30 = 75
3 u = 75 - 30
3 u = 45
1 u = 45 ÷ 3 = $15
Amount that Usha spent
= 1 u
= 15
(b)
Amount that Linda spent
= 1 u + 18
= 15 + 18
= $33
Answer(s): (a) $15; (b) $33
