During the 2016 christmas season,UPS had 14 employees retire, 122 employees were hired and 31 left due to illness. If UPS ended the year with 410 employees, how many did they have at the start of the season?

Let x be the number of employees at the start of the season. We have:

• -14 since retiring is an employee loss
• +122 hired since hiring is an employee gain
• -31 since illness means a leave

x - 14 + 122 - 31 = 410

Using our equation solver, we get:
x = 333
