Before |
8 u |
+ 352 |
8x5 = 40 u |
2080 |
Change |
- 5 u |
- 220 |
- 1x5 = - 5 u |
|
Comparing the laptop and the notebook |
220 more |
|
|
After |
3 u |
+ 132 |
7x5 = 35 u |
|
220 ÷ 5 = 44
3 x 44 = 132
8 x 44 = 352
Total amount that Brandon and Owen had at first
= 8 u + 352 + 40 u
= 48 u + 352
48 u + 352 = 2080
48 u = 2080 - 352
48 u = 1728
1 u = 1728 ÷ 48 = 36
Amount that Brandon had left
= 3 u + 132
= 3 x 36 + 132
= 108 + 132
= $240
Answer(s): $240
