Before |
5 u |
+ 725 |
6x2 = 12 u |
1201 |
Change |
- 2 u |
- 290 |
- 1x2 = - 2 u |
|
Comparing the computer and the television |
290 more |
|
|
After |
3 u |
+ 435 |
5x2 = 10 u |
|
290 ÷ 2 = 145
3 x 145 = 435
5 x 145 = 725
Total amount that Tommy and Cole had at first
= 5 u + 725 + 12 u
= 17 u + 725
17 u + 725 = 1201
17 u = 1201 - 725
17 u = 476
1 u = 476 ÷ 17 = 28
Amount that Tommy had left
= 3 u + 435
= 3 x 28 + 435
= 84 + 435
= $519
Answer(s): $519
