For the next seven months, he continued to have the same monthly paycheck.
In the last two months, he received a monthly paycheck that was $250 more than his previous paycheck.
First, let's calculate the monthly paycheck for the first three months:
Total earnings for the first three months = $5,568
Monthly paycheck for the first three months = $5,568 / 3 = $1,856
Now, the employee received the same paycheck for the next seven months:
Monthly paycheck for the next seven months = $1,856
Total earnings for the next seven months = 7 months * $1,856/month = $12,992
Finally, in the last two months, the employee received a paycheck that was $250 more than before:
Monthly paycheck for the last two months = $1,856 + $250 = $2,106
Total earnings for the last two months = 2 months * $2,106/month = $4,212
Now, let's calculate the employee's total earnings for the entire year:
Total earnings for the first three months + Total earnings for the next seven months + Total earnings for the last two months
$5,568 + $12,992 + $4,212 = $22,772
So, the employee made a total of $22,772 in his first year on the job.
