Comparing the laptop

117 more |
|
|
After |
2 u |
+ 78 |
4x3 =
12 u |
|
117 ÷ 3 = 39
2 x 39 = 78
5 x 39 = 195
Total amount that Nick and Elijah had at first
= 5 u + 195 + 15 u
= 20 u + 195
20 u + 195 = 875
20 u = 875 - 195
20 u = 680
1 u = 680 ÷ 20 = 34
Amount that Nick had at first
= 5 u + 195
= 5 x 34 + 195
= 170 + 195
= $365
Answer(s): $365
