Three brothers spent a total of $96. Abi spent $10 more than Nora and Eva spent $7 more than Abi.
- How much money did Nora spend?
- How much money did Eva spend?
(a)
Amount that Nora spent = 1 u
Amount that Abi spent = 1 u + 10
Amount that Eva spent = 1 u + 10 + 7 = 1 u + 17
Total amount that they spent
= 1 u + 1 u + 10 + 1 u + 17
= 3 u + 27
3 u + 27 = 96
3 u = 96 - 27
3 u = 69
1 u = 69 ÷ 3 = $23
Amount that Nora spent
= 1 u
= 23
(b)
Amount that Eva spent
= 1 u + 17
= 23 + 17
= $40
Answer(s): (a) $23; (b) $40
