Mr. Pang employed some welders and painters for his construction site. A painter was paid $8 a day and a welder was paid $14 a day. Given that he employed 4 times as many welders as painters and a total of $256 was paid to these workers for the day, how many more welders than painters did Mr. Pang employ for his site?

Number of painters = 1 u
Number of welders = 4 x 1 u = 4 u
Total amount paid
= (4 u x 14) + (1 u x 8)
= 56 u + 8 u
= 64 u
64 u = 256
1 u = 256 ÷ 64 = 4
Number of more welders than painters
= 4 u - 1 u
= 3 u
= 3 x 4
= 12
Answer(s): 12
