Mr. Choy employed some painters and plumbers for his construction site. A plumber was paid $9 a day and a painter was paid $14 a day. Given that he employed 5 times as many painters as plumbers and a total of $158 was paid to these workers for the day, how many more painters than plumbers did Mr. Choy employ for his site?

79 u |
Number of plumbers = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 14) + (1 u x 9)
= 70 u + 9 u
= 79 u
79 u = 158
1 u = 158 ÷ 79 = 2
Number of more painters than plumbers
= 5 u - 1 u
= 4 u
= 4 x 2
= 8
Answer(s): 8
