Three brothers spent a total of $76. Kylie spent $8 more than Roshel and Vanessa spent $15 more than Kylie.
- How much money did Roshel spend?
- How much money did Vanessa spend?
(a)
Amount that Roshel spent = 1 u
Amount that Kylie spent = 1 u + 8
Amount that Vanessa spent = 1 u + 8 + 15 = 1 u + 23
Total amount that they spent
= 1 u + 1 u + 8 + 1 u + 23
= 3 u + 31
3 u + 31 = 76
3 u = 76 - 31
3 u = 45
1 u = 45 ÷ 3 = $15
Amount that Roshel spent
= 1 u
= 15
(b)
Amount that Vanessa spent
= 1 u + 23
= 15 + 23
= $38
Answer(s): (a) $15; (b) $38
