Three brothers spent a total of $76. Hazel spent $7 more than Yen and Kylie spent $14 more than Hazel.
- How much money did Yen spend?
- How much money did Kylie spend?
(a)
Amount that Yen spent = 1 u
Amount that Hazel spent = 1 u + 7
Amount that Kylie spent = 1 u + 7 + 14 = 1 u + 21
Total amount that they spent
= 1 u + 1 u + 7 + 1 u + 21
= 3 u + 28
3 u + 28 = 76
3 u = 76 - 28
3 u = 48
1 u = 48 ÷ 3 = $16
Amount that Yen spent
= 1 u
= 16
(b)
Amount that Kylie spent
= 1 u + 21
= 16 + 21
= $37
Answer(s): (a) $16; (b) $37
