Before |
5 u |
+ 630 |
8x2 = 16 u |

Change |
- 2 u |
- 252 |
- 1x2 = - 2 u |

Comparing the television and the refrigerator |
252 more |
|
|
After |
3 u |
+ 378 |
7x2 = 14 u |
|
252 ÷ 2 = 126
3 x 126 = 378
5 x 126 = 630
Total amount that Luke and Fabian had at first
= 5 u + 630 + 16 u
= 21 u + 630
21 u + 630 = 1071
21 u = 1071 - 630
21 u = 441
1 u = 441 ÷ 21 = 21
Amount that Luke had at first
= 5 u + 630
= 5 x 21 + 630
= 105 + 630
= $735
Answer(s): $735
