Three schoolmates spent a total of $70. Jaslyn spent $8 more than Lucy and Jen spent $6 more than Jaslyn.
- How much money did Lucy spend?
- How much money did Jen spend?
(a)
Amount that Lucy spent = 1 u
Amount that Jaslyn spent = 1 u + 8
Amount that Jen spent = 1 u + 8 + 6 = 1 u + 14
Total amount that they spent
= 1 u + 1 u + 8 + 1 u + 14
= 3 u + 22
3 u + 22 = 70
3 u = 70 - 22
3 u = 48
1 u = 48 ÷ 3 = $16
Amount that Lucy spent
= 1 u
= 16
(b)
Amount that Jen spent
= 1 u + 14
= 16 + 14
= $30
Answer(s): (a) $16; (b) $30
