Question 1123860
<br>
(1) By logical reasoning....<br>
His sales in the 6th month have to be $85000, plus an extra $3000 for each of the 6 months.<br>
$85000 + 6($3000) = $85000+$18000 = $103000<br>
Using algebra....<br>
"5 months with an average of $85000, plus the next month with x, makes an average of $88000 ($85000+$3000) for 6 months":<br>
5(85000)+x = 6(88000)
425000+x = 528000
x = 5528000-425000 = 103000
