Comparing the notebook

186 more |
|
|
After |
3 u |
+ 279 |
5x2 =
10 u |
|
186 ÷ 2 = 93
3 x 93 = 279
5 x 93 = 465
Total amount that Lee and Caden had at first
= 5 u + 465 + 12 u
= 17 u + 465
17 u + 465 = 1026
17 u = 1026 - 465
17 u = 561
1 u = 561 ÷ 17 = 33
Amount that Lee had at first
= 5 u + 465
= 5 x 33 + 465
= 165 + 465
= $630
Answer(s): $630
