Mr. Seow 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 3 times as many painters as welders and a total of $106 was paid to these workers for the day, how many more painters than welders did Mr. Seow employ for his site?

Number of welders = 1 u
Number of painters = 3 x 1 u = 3 u
Total amount paid
= (3 u x 16) + (1 u x 5)
= 48 u + 5 u
= 53 u
53 u = 106
1 u = 106 ÷ 53 = 2
Number of more painters than welders
= 3 u - 1 u
= 2 u
= 2 x 2
= 4
Answer(s): 4
