Mr. Kok employed some painters and welders for his construction site. A welder was paid $5 a day and a painter was paid $16 a day. Given that he employed 5 times as many painters as welders and a total of $255 was paid to these workers for the day, how many more painters than welders did Mr. Kok employ for his site?

Number of welders = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 16) + (1 u x 5)
= 80 u + 5 u
= 85 u
85 u = 255
1 u = 255 ÷ 85 = 3
Number of more painters than welders
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
