Mr. Loh employed some welders and painters for his construction site. A painter was paid $10 a day and a welder was paid $14 a day. Given that he employed 5 times as many welders as painters and a total of $160 was paid to these workers for the day, how many more welders than painters did Mr. Loh employ for his site?

Number of painters = 1 u
Number of welders = 5 x 1 u = 5 u
Total amount paid
= (5 u x 14) + (1 u x 10)
= 70 u + 10 u
= 80 u
80 u = 160
1 u = 160 ÷ 80 = 2
Number of more welders than painters
= 5 u - 1 u
= 4 u
= 4 x 2
= 8
Answer(s): 8
