Answer:

Option D $26,792

Step-by-step explanation:

When producing 427 printers, the cost of production is 427*$48.28=$20,615.56

When selling each printer, profit per printer is $163.95 - $48.28= $115.67

Total money after selling the 427 printers is 427*$163.95 =$70006.65

Subtracting cost of production from value of sales we deduce

$70006.65-$20,615.56=$49391.09

Non-profit overhead expenses will be the difference between the expected profit and the actual profit earned

$49391.09 -$22,599.09.=$26,792

Therefore, option D, $26,792 is the right choice

Solve for k: 8k + 2m=3m+4

Andreyy89

Isolate the k. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2m from both sides

8k + 2m (-2m) = 3m (-2m) + 4

8k = m + 4

Next, divide 8 from both sides

(8k)/8 = (m + 4)/8

k = (m + 4)/8

k = m/8 + 1/2

k = m/8 + 1/2 is your answer

hope this helps
