Three classmates spent a total of $59. Esther spent $12 more than Ivory and Tammy spent $14 more than Esther.
- How much money did Ivory spend?
- How much money did Tammy spend?
(a)
Amount that Ivory spent = 1 u
Amount that Esther spent = 1 u + 12
Amount that Tammy spent = 1 u + 12 + 14 = 1 u + 26
Total amount that they spent
= 1 u + 1 u + 12 + 1 u + 26
= 3 u + 38
3 u + 38 = 59
3 u = 59 - 38
3 u = 21
1 u = 21 ÷ 3 = $7
Amount that Ivory spent
= 1 u
= 7
(b)
Amount that Tammy spent
= 1 u + 26
= 7 + 26
= $33
Answer(s): (a) $7; (b) $33
