Mr. Tang employed some painters and plumbers for his construction site. A plumber was paid $8 a day and a painter was paid $12 a day. Given that he employed 5 times as many painters as plumbers and a total of $272 was paid to these workers for the day, how many less painters than plumbers did Mr. Tang employ for his site?

68 u |
Number of plumbers = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 12) + (1 u x 8)
= 60 u + 8 u
= 68 u
68 u = 272
1 u = 272 ÷ 68 = 4
Number of less plumbers than painters
= 5 u - 1 u
= 4 u
= 4 x 4
= 16
Answer(s): 16
