Before |
9 u |
+ 513 |
4x5 = 20 u |
1586 |
Change |
- 5 u |
- 285 |
- 1x5 = - 5 u |
|
Comparing the refrigerator and the laptop |
285 more |
|
|
After |
4 u |
+ 228 |
3x5 = 15 u |
|
285 ÷ 5 = 57
4 x 57 = 228
9 x 57 = 513
Total amount that Harry and Justin had at first
= 9 u + 513 + 20 u
= 29 u + 513
29 u + 513 = 1586
29 u = 1586 - 513
29 u = 1073
1 u = 1073 ÷ 29 = 37
Amount that Harry had left
= 4 u + 228
= 4 x 37 + 228
= 148 + 228
= $376
Answer(s): $376
