Comparing the notebook
and the laptop |
250 more |
|
|
After |
3 u |
+ 150 |
6x5 =
30 u |
|
250 ÷ 5 = 50
3 x 50 = 150
8 x 50 = 400
Total amount that Andy and Harry had at first
= 8 u + 400 + 35 u
= 43 u + 400
43 u + 400 = 1432
43 u = 1432 - 400
43 u = 1032
1 u = 1032 ÷ 43 = 24
Amount that Andy had left
= 3 u + 150
= 3 x 24 + 150
= 72 + 150
= $222
Answer(s): $222
