Answer:
c = $30 + $0.75p
Step-by-step explanation:
total cost = total fixed cost + total variable cost
total fixed cost = $30
Fixed costs are costs that do not vary with output.
total variable cost = variable cost per unit x total unit
p x 0.75
Variable costs are costs that vary with production
divide 60 by 12
60/12 = 5
multiply that by 3
5*3 = 15
so they will show 15 commercials every 60 minutes
To be able to solve clearly this problem, the best thing
to do is to plot the graph (see attached pic). From the graph we can see that
the points form a trapezoid.
The base is formed by the segment connecting point A and
point B.
While the two heights: shorter one by the segment
connecting points A and D, and the longer one by the segment connecting points
B and C.
The formula for area of trapezoid is given as:
A = b (h1 + h2) / 2
Where,
<span>b = base of the trapezoid
= 3 – (-4) = 7</span>
h1 = shorter height = 2 – (-2) = 4
h2 = longer height = 2 – (-5) = 7
Therefore the area is:
A = 7 (4 + 7) / 2
A = 77 / 2
<span>A = 38.5 </span>
It would be 105,600 yards because if you multiply 1760 and 60 you’d get 105,600
