Comparing the portable air-conditioner

144 more |
|
|
After |
2 u |
+ 96 |
5x3 =
15 u |
|
144 ÷ 3 = 48
2 x 48 = 96
5 x 48 = 240
Total amount that Lee and Valen had at first
= 5 u + 240 + 18 u
= 23 u + 240
23 u + 240 = 1068
23 u = 1068 - 240
23 u = 828
1 u = 828 ÷ 23 = 36
Amount that Lee had left
= 2 u + 96
= 2 x 36 + 96
= 72 + 96
= $168
Answer(s): $168
