Mr. Long employed some painters and welders for his construction site. A welder was paid $6 a day and a painter was paid $12 a day. Given that he employed 4 times as many painters as welders and a total of $270 was paid to these workers for the day, how many less painters than welders did Mr. Long employ for his site?

Number of welders = 1 u
Number of painters = 4 x 1 u = 4 u
Total amount paid
= (4 u x 12) + (1 u x 6)
= 48 u + 6 u
= 54 u
54 u = 270
1 u = 270 ÷ 54 = 5
Number of less welders than painters
= 4 u - 1 u
= 3 u
= 3 x 5
= 15
Answer(s): 15
