Mr. Chen employed some painters and plumbers for his construction site. A plumber was paid $9 a day and a painter was paid $17 a day. Given that he employed 5 times as many painters as plumbers and a total of $282 was paid to these workers for the day, how many more painters than plumbers did Mr. Chen employ for his site?

94 u |
Number of plumbers = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 17) + (1 u x 9)
= 85 u + 9 u
= 94 u
94 u = 282
1 u = 282 ÷ 94 = 3
Number of more painters than plumbers
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
