Mr. Chew employed some painters and plumbers for his construction site. A plumber was paid $8 a day and a painter was paid $17 a day. Given that he employed 3 times as many painters as plumbers and a total of $236 was paid to these workers for the day, how many more painters than plumbers did Mr. Chew employ for his site?

Number of plumbers = 1 u
Number of painters = 3 x 1 u = 3 u
Total amount paid
= (3 u x 17) + (1 u x 8)
= 51 u + 8 u
= 59 u
59 u = 236
1 u = 236 ÷ 59 = 4
Number of more painters than plumbers
= 3 u - 1 u
= 2 u
= 2 x 4
= 8
Answer(s): 8
