The cost of the refrigerator is repeated. Make the cost of the refrigerator the same. LCM of 4, 5 and 7 is 140.
Amount that Asher had
= 140 u - (35 u + 28 u + 20 u)
= 57 u
Amount that Asher paid more than Glen
= 57 u - 35 u
= 22 u
22 u = 176
1 u = 176 ÷ 22 = 8
Cost of the refrigerator
= 140 u
= 140 x 8
= $1120
Answer(s): $1120
