Mr. Loo employed some painters and plumbers for his construction site. A plumber was paid $10 a day and a painter was paid $14 a day. Given that he employed 3 times as many painters as plumbers and a total of $208 was paid to these workers for the day, how many less painters than plumbers did Mr. Loo employ for his site?

Number of plumbers = 1 u
Number of painters = 3 x 1 u = 3 u
Total amount paid
= (3 u x 14) + (1 u x 10)
= 42 u + 10 u
= 52 u
52 u = 208
1 u = 208 ÷ 52 = 4
Number of less plumbers than painters
= 3 u - 1 u
= 2 u
= 2 x 4
= 8
Answer(s): 8
