Mr. Tay 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 5 times as many welders as painters and a total of $234 was paid to these workers for the day, how many less welders than painters did Mr. Tay 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 8)
= 70 u + 8 u
= 78 u
78 u = 234
1 u = 234 ÷ 78 = 3
Number of less painters than welders
= 5 u - 1 u
= 4 u
= 4 x 3
= 12
Answer(s): 12
