Before |
8 u |
+ 592 |
7x3 = 21 u |
1433 |
Change |
- 3 u |
- 222 |
- 1x3 = - 3 u |
|
Comparing the laptop and the dishwasher |
222 more |
|
|
After |
5 u |
+ 370 |
6x3 = 18 u |
|
222 ÷ 3 = 74
5 x 74 = 370
8 x 74 = 592
Total amount that Warren and Reggie had at first
= 8 u + 592 + 21 u
= 29 u + 592
29 u + 592 = 1433
29 u = 1433 - 592
29 u = 841
1 u = 841 ÷ 29 = 29
Amount that Warren had at first
= 8 u + 592
= 8 x 29 + 592
= 232 + 592
= $824
Answer(s): $824
