The cost of the washing machine is repeated. Make the cost of the washing machine the same. LCM of 4, 6 and 8 is 24.
Amount that Howard had
= 24 u - (6 u + 4 u + 3 u)
= 11 u
Amount that Howard paid more than Billy
= 11 u - 6 u
= 5 u
5 u = 35
1 u = 35 ÷ 5 = 7
Cost of the washing machine
= 24 u
= 24 x 7
= $168
Answer(s): $168
