Total |
Before |
8 u |
+ 496 |
6x3 = 18 u |
1068 |
Change |
- 3 u |
- 186 |
- 1x3 = - 3 u |
|
Comparing the notebook and the dishwasher |
186 more |
|
|
After |
5 u |
+ 310 |
5x3 = 15 u |
|
186 ÷ 3 = 62
5 x 62 = 310
8 x 62 = 496
Total amount that Harry and Tommy had at first
= 8 u + 496 + 18 u
= 26 u + 496
26 u + 496 = 1068
26 u = 1068 - 496
26 u = 572
1 u = 572 ÷ 26 = 22
Amount that Harry had left
= 5 u + 310
= 5 x 22 + 310
= 110 + 310
= $420
Answer(s): $420
