Comparing the refrigerator

|
|
After |
3 u |
+ 267 |
7x2 =
14 u |
|
178 ÷ 2 = 89
3 x 89 = 267
5 x 89 = 445
Total amount that Michael and Asher had at first
= 5 u + 445 + 16 u
= 21 u + 445
21 u + 445 = 865
21 u = 865 - 445
21 u = 420
1 u = 420 ÷ 21 = 20
Amount that Michael had at first
= 5 u + 445
= 5 x 20 + 445
= 100 + 445
= $545
Answer(s): $545
