Answer:
The contribution margin it's determined by the total amount of Gross Profit divided by the total value of sales.
Profit = $405,000
Sales = 11,250×106 =$1,192,500
Therefore contribution margin ratio = ($405,000/$1,192,500) = 0.34
The Break Even point is given thus;
Fixed cost = 25 × 11250 =$281,250
Break-even point = Fixed costs ÷ contribution ratio
= $281,250/0.34 = $827,205.88
Answer:

Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
so
The distance is equal to multiply the speed by the time
we have



Convert mixed number to an improper fraction


substitute

Convert to mixed number

B) lograrithmic
this is obvious since it is increasing at decreasing rate
As given by the question
There are given that the point of two-line

Now,
From the condition of a parallel and perpendicular line
If the slopes are equal then the lines are parallel
If the slopes are negative reciprocal then the lines are perpendicular
If the slopes are neither of the above are true then lines are neither
Then,
First, find the slope of both of line
So,
For first-line, from the formula of slope

Now,
For second-line,

The given result of the slope is negative reciprocal because

Hence, the slope of line1 is -1/2, and slope of line2 is 2 and the lines are perpendicular.
