Three colleagues spent a total of $56. Dana spent $5 more than Yen and Usha spent $10 more than Dana.
- How much money did Yen spend?
- How much money did Usha spend?
(a)
Amount that Yen spent = 1 u
Amount that Dana spent = 1 u + 5
Amount that Usha spent = 1 u + 5 + 10 = 1 u + 15
Total amount that they spent
= 1 u + 1 u + 5 + 1 u + 15
= 3 u + 20
3 u + 20 = 56
3 u = 56 - 20
3 u = 36
1 u = 36 ÷ 3 = $12
Amount that Yen spent
= 1 u
= 12
(b)
Amount that Usha spent
= 1 u + 15
= 12 + 15
= $27
Answer(s): (a) $12; (b) $27
