Mr. Oh employed some painters and plumbers for his construction site. A plumber was paid $8 a day and a painter was paid $19 a day. Given that he employed 5 times as many painters as plumbers and a total of $206 was paid to these workers for the day, how many more painters than plumbers did Mr. Oh employ for his site?

103 u |
Number of plumbers = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 19) + (1 u x 8)
= 95 u + 8 u
= 103 u
103 u = 206
1 u = 206 ÷ 103 = 2
Number of more painters than plumbers
= 5 u - 1 u
= 4 u
= 4 x 2
= 8
Answer(s): 8
