Total |
Before |
5 u |
+ 590 |
5x2 = 10 u |
965 |
Change |
- 2 u |
- 236 |
- 1x2 = - 2 u |
|
Comparing the refrigerator and the dishwasher |
236 more |
|
|
After |
3 u |
+ 354 |
4x2 = 8 u |
|
236 ÷ 2 = 118
3 x 118 = 354
5 x 118 = 590
Total amount that George and Jack had at first
= 5 u + 590 + 10 u
= 15 u + 590
15 u + 590 = 965
15 u = 965 - 590
15 u = 375
1 u = 375 ÷ 15 = 25
Amount that George had left
= 3 u + 354
= 3 x 25 + 354
= 75 + 354
= $429
Answer(s): $429
