To find: the number of workers at the beginning of the year.

Answer to Problem 13P
There 454 workers at the beginning of the year.
Explanation of Solution
Given information:
A factory hired 130 new workers during a year in which 27 workers retired and 59 left for the other reasons. There were 198 workers at the end of the year.
Calculation:
Let, consider that
A factory hired 130 new workers during a year in which 27 workers retired and 59 left for the other reasons. There were 198 workers at the end of the year.
So, as per given information, write the equation as,
Now, solve the equation as shown,
Hence, there 454 workers at the beginning of the year.
