(1) By logical reasoning....

His sales in the 6th month have to be $85000, plus an extra $3000 for each of the 6 months.

$85000 + 6($3000) = $85000+$18000 = $103000

Using algebra....

"5 months with an average of $85000, plus the next month with x, makes an average of $88000 ($85000+$3000) for 6 months":

5(85000)+x = 6(88000)
425000+x = 528000
x = 5528000-425000 = 103000
