Mr. Chong employed some welders and painters for his construction site. A painter was paid $6 a day and a welder was paid $17 a day. Given that he employed 5 times as many welders as painters and a total of $273 was paid to these workers for the day, how many less welders than painters did Mr. Chong employ for his site?

Number of painters = 1 u
Number of welders = 5 x 1 u = 5 u
Total amount paid
= (5 u x 17) + (1 u x 6)
= 85 u + 6 u
= 91 u
91 u = 273
1 u = 273 ÷ 91 = 3
Number of less painters than welders
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
