Comparing the washing machine
and the laptop |
267 more |
|
|
After |
5 u |
+ 445 |
3x3 =
9 u |
|
267 ÷ 3 = 89
5 x 89 = 445
8 x 89 = 712
Total amount that Fred and John had at first
= 8 u + 712 + 12 u
= 20 u + 712
20 u + 712 = 1192
20 u = 1192 - 712
20 u = 480
1 u = 480 ÷ 20 = 24
Amount that Fred had left
= 5 u + 445
= 5 x 24 + 445
= 120 + 445
= $565
Answer(s): $565
