Three schoolmates spent a total of $63. Julie spent $11 more than Lynn and Kimberly spent $14 more than Julie.
- How much money did Lynn spend?
- How much money did Kimberly spend?
(a)
Amount that Lynn spent = 1 u
Amount that Julie spent = 1 u + 11
Amount that Kimberly spent = 1 u + 11 + 14 = 1 u + 25
Total amount that they spent
= 1 u + 1 u + 11 + 1 u + 25
= 3 u + 36
3 u + 36 = 63
3 u = 63 - 36
3 u = 27
1 u = 27 ÷ 3 = $9
Amount that Lynn spent
= 1 u
= 9
(b)
Amount that Kimberly spent
= 1 u + 25
= 9 + 25
= $34
Answer(s): (a) $9; (b) $34
