Comparing the computer
and the dishwasher |
288 more |
|
|
After |
2 u |
+ 192 |
5x3 =
15 u |
|
288 ÷ 3 = 96
2 x 96 = 192
5 x 96 = 480
Total amount that Archie and Fabian had at first
= 5 u + 480 + 18 u
= 23 u + 480
23 u + 480 = 1331
23 u = 1331 - 480
23 u = 851
1 u = 851 ÷ 23 = 37
Amount that Archie had at first
= 5 u + 480
= 5 x 37 + 480
= 185 + 480
= $665
Answer(s): $665
