Mr. Sih employed some painters and welders for his construction site. A welder was paid $10 a day and a painter was paid $13 a day. Given that he employed 3 times as many painters as welders and a total of $147 was paid to these workers for the day, how many more painters than welders did Mr. Sih employ for his site?

Number of welders = 1 u
Number of painters = 3 x 1 u = 3 u
Total amount paid
= (3 u x 13) + (1 u x 10)
= 39 u + 10 u
= 49 u
49 u = 147
1 u = 147 ÷ 49 = 3
Number of more painters than welders
= 3 u - 1 u
= 2 u
= 2 x 3
= 6
Answer(s): 6
