Kevin works for a company which produces printers. A printer sells for $163.95 and costs $48.28 to produce. In one month, Kevin’

victus00 [196]

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

professor190 [17]

Answer:

a. $Savings = \$16$

b. $Price = \$96$

Step-by-step explanation:

Solving (a):

$Price = \$80$

$Coupon = 20\%$

Required

Determine her savings.

$Savings = Coupon * Price$

$Savings = 20\% * \$80$

$Savings = \$16$

Solving (a):

$Price = \$120$

$Coupon = 20\%$

Required

Determine the price before tax

First, we need to determine her savings

$Savings = Coupon * Price$

$Savings = 20\% * \$120$

$Savings = \$24$

The price before tax is calculated as follows:

$Price = \$120 - \$24$

$Price = \$96$

What is the vertex of y=-6(2.5-x)(x-5.5)?

Alex787 [66]

Hello :

<span> y=-6(2.5-x)(x-5.5) = -6(2.5x -13.75 -x² +5.5x)
y = -6(-x²+8x -13.75)
y = 6x²-48x+82.5
note :
if f(x) = ax²+bx +c the vertex is the point : ( -b/2a ; f(-b/2a))
a=6 b=-48 c = 82.5 .......calculate
-b/2a = -(-48)/2(6)= 4
f(4) =6(4)²-48(4)+82.5 =96 - 192 +82.5 = -13.5</span>
