Mr. Tang employed some painters and welders for his construction site. A welder was paid $5 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 $212 was paid to these workers for the day, how many more painters than welders did Mr. Tang 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 5)
= 48 u + 5 u
= 53 u
53 u = 212
1 u = 212 ÷ 53 = 4
Number of more painters than welders
= 4 u - 1 u
= 3 u
= 3 x 4
= 12
Answer(s): 12
