Comparing the laptop

284 more |
|
|
After |
3 u |
+ 426 |
7x2 =
14 u |
|
284 ÷ 2 = 142
3 x 142 = 426
5 x 142 = 710
Total amount that Cole and Asher had at first
= 5 u + 710 + 16 u
= 21 u + 710
21 u + 710 = 1361
21 u = 1361 - 710
21 u = 651
1 u = 651 ÷ 21 = 31
Amount that Cole had at first
= 5 u + 710
= 5 x 31 + 710
= 155 + 710
= $865
Answer(s): $865
