Before |
9 u |
+ 225 |
4x5 = 20 u |
950 |
Change |
- 5 u |
- 125 |
- 1x5 = - 5 u |
|
Comparing the refrigerator and the laptop |
125 more |
|
|
After |
4 u |
+ 100 |
3x5 = 15 u |
|
125 ÷ 5 = 25
4 x 25 = 100
9 x 25 = 225
Total amount that Howard and Sam had at first
= 9 u + 225 + 20 u
= 29 u + 225
29 u + 225 = 950
29 u = 950 - 225
29 u = 725
1 u = 725 ÷ 29 = 25
Amount that Howard had at first
= 9 u + 225
= 9 x 25 + 225
= 225 + 225
= $450
Answer(s): $450
