Comparing the notebook
and the television |
300 more |
|
|
After |
5 u |
+ 500 |
2x3 =
6 u |
|
300 ÷ 3 = 100
5 x 100 = 500
8 x 100 = 800
Total amount that Ben and Liam had at first
= 8 u + 800 + 9 u
= 17 u + 800
17 u + 800 = 1174
17 u = 1174 - 800
17 u = 374
1 u = 374 ÷ 17 = 22
Amount that Ben had left
= 5 u + 500
= 5 x 22 + 500
= 110 + 500
= $610
Answer(s): $610
