Mr. Yap employed some painters and plumbers for his construction site. A plumber was paid $5 a day and a painter was paid $15 a day. Given that he employed 4 times as many painters as plumbers and a total of $260 was paid to these workers for the day, how many more painters than plumbers did Mr. Yap employ for his site?

Number of plumbers = 1 u
Number of painters = 4 x 1 u = 4 u
Total amount paid
= (4 u x 15) + (1 u x 5)
= 60 u + 5 u
= 65 u
65 u = 260
1 u = 260 ÷ 65 = 4
Number of more painters than plumbers
= 4 u - 1 u
= 3 u
= 3 x 4
= 12
Answer(s): 12
