- 1x5 = - 5 u |

Comparing the refrigerator and the home theater system |
215 more |
|
|
After |
4 u |
+ 172 |
3x5 = 15 u |
|
215 ÷ 5 = 43
4 x 43 = 172
9 x 43 = 387
Total amount that Glen and Paul had at first
= 9 u + 387 + 20 u
= 29 u + 387
29 u + 387 = 1083
29 u = 1083 - 387
29 u = 696
1 u = 696 ÷ 29 = 24
Amount that Glen had at first
= 9 u + 387
= 9 x 24 + 387
= 216 + 387
= $603
Answer(s): $603
