Three colleagues spent a total of $57. Wendy spent $11 more than Raeann and Yen spent $11 more than Wendy.
- How much money did Raeann spend?
- How much money did Yen spend?
(a)
Amount that Raeann spent = 1 u
Amount that Wendy spent = 1 u + 11
Amount that Yen spent = 1 u + 11 + 11 = 1 u + 22
Total amount that they spent
= 1 u + 1 u + 11 + 1 u + 22
= 3 u + 33
3 u + 33 = 57
3 u = 57 - 33
3 u = 24
1 u = 24 ÷ 3 = $8
Amount that Raeann spent
= 1 u
= 8
(b)
Amount that Yen spent
= 1 u + 22
= 8 + 22
= $30
Answer(s): (a) $8; (b) $30
