Comparing the dishwasher
and the computer |
183 more |
|
|
After |
2 u |
+ 122 |
3x3 =
9 u |
|
183 ÷ 3 = 61
2 x 61 = 122
5 x 61 = 305
Total amount that Tom and Luke had at first
= 5 u + 305 + 12 u
= 17 u + 305
17 u + 305 = 951
17 u = 951 - 305
17 u = 646
1 u = 646 ÷ 17 = 38
Amount that Tom had at first
= 5 u + 305
= 5 x 38 + 305
= 190 + 305
= $495
Answer(s): $495
