Comparing the portable air-conditioner

105 more |
|
|
After |
2 u |
+ 70 |
5x3 =
15 u |
|
105 ÷ 3 = 35
2 x 35 = 70
5 x 35 = 175
Total amount that Ryan and Lee had at first
= 5 u + 175 + 18 u
= 23 u + 175
23 u + 175 = 773
23 u = 773 - 175
23 u = 598
1 u = 598 ÷ 23 = 26
Amount that Ryan had at first
= 5 u + 175
= 5 x 26 + 175
= 130 + 175
= $305
Answer(s): $305
