The cost of the refrigerator is repeated. Make the cost of the refrigerator the same. LCM of 4, 6 and 8 is 24.
Amount that Gabriel had
= 24 u - (6 u + 4 u + 3 u)
= 11 u
Amount that Gabriel paid more than Will
= 11 u - 6 u
= 5 u
5 u = 50
1 u = 50 ÷ 5 = 10
Cost of the refrigerator
= 24 u
= 24 x 10
= $240
Answer(s): $240
