Mr. Tay 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 3 times as many painters as welders and a total of $123 was paid to these workers for the day, how many more painters than welders did Mr. Tay employ for his site?

41 u |
Number of welders = 1 u
Number of painters = 3 x 1 u = 3 u
Total amount paid
= (3 u x 12) + (1 u x 5)
= 36 u + 5 u
= 41 u
41 u = 123
1 u = 123 ÷ 41 = 3
Number of more painters than welders
= 3 u - 1 u
= 2 u
= 2 x 3
= 6
Answer(s): 6
