Mr. Ee employed some plumbers and painters for his construction site. A painter was paid $5 a day and a plumber was paid $14 a day. Given that he employed 4 times as many plumbers as painters and a total of $183 was paid to these workers for the day, how many more plumbers than painters did Mr. Ee employ for his site?

Number of painters = 1 u
Number of plumbers = 4 x 1 u = 4 u
Total amount paid
= (4 u x 14) + (1 u x 5)
= 56 u + 5 u
= 61 u
61 u = 183
1 u = 183 ÷ 61 = 3
Number of more plumbers than painters
= 4 u - 1 u
= 3 u
= 3 x 3
= 9
Answer(s): 9
