The average salary of employees at an advertising firm with ๐ employees in thousands of dollars is 53
Total = \(53P\)
The average salary of employees at an advertising firm with ๐ employees in thousands of dollars is 95.
Total = \(95Q\)
When the salaries of both firms are combined, the average salary in thousands of dollars is 83.
Total = \(83(P + Q)\)
\(53 P + 95 Q = 83(P + Q)\)
\(12 Q = 30 P\)
\(\frac{P}{Q}\) = \(\frac{2}{5}\)
Total = \(53P\)
