Find number of each type of worker

Question

there are 22 full-time employees. New employees receive $9.50 per hour, while more experienced workers average $12.90 per hour. the company spends $273.60 per hour in wages. find the number of each type of worker.

Answer 1

n + m = 22 --------> n = 22 - m

9.5n + 12.9m = 273.6

 

9.5(22 - m) + 12.9m= 273.6

209 - 9.5m + 12.9m = 273.6

3.4m = 64.6

m = 19

 

n = 22 - 19 = 3
