The cost of the television is repeated. Make the cost of the television the same. LCM of 4, 5 and 6 is 60.
Amount that Michael had
= 60 u - (15 u + 12 u + 10 u)
= 23 u
Amount that Michael paid more than Gabriel
= 23 u - 15 u
= 8 u
8 u = 24
1 u = 24 ÷ 8 = 3
Cost of the television
= 60 u
= 60 x 3
= $180
Answer(s): $180
