Comparing the washing machine

180 more |
|
|
After |
5 u |
+ 225 |
3x4 =
12 u |
|
180 ÷ 4 = 45
5 x 45 = 225
9 x 45 = 405
Total amount that Jenson and Wesley had at first
= 9 u + 405 + 16 u
= 25 u + 405
25 u + 405 = 1330
25 u = 1330 - 405
25 u = 925
1 u = 925 ÷ 25 = 37
Amount that Jenson had left
= 5 u + 225
= 5 x 37 + 225
= 185 + 225
= $410
Answer(s): $410
