Answer:

Step-by-step explanation:
The area of an rectangle is given by the following formula:

Where:
- Width, in centimeters.
- Height, in centimeters.
The differential of the expression is derived hereafter:




Answer:
B
Step-by-step explanation:
Area = L * W
L = 12 m
W = 10 m
Area = 12 m * 10 m
Area = 120 m^2
-9 1/12
First change it into an improper fraction by multiplying the whole number by the denominator and then adding it to the numerator.
108/12
Now simplify that by dividing them to get the quotient.
108/12 = 9
Given is the Overhead charges = 25 dollars.
Making charge of each barrette = 1.25 dollars.
Let's assume the number of barrette that she makes = x
So the Cost function would be, C(x) = 1.25x + 25.
She sell each piece for 3.50 dollars.
So the Revenue function would be, R(x) = 3.50x
We know the Profit function is given by the difference of Revenue function and Cost function.
Profit function = Revenue function - Cost function
P(x) = R(x) - C(x)
P(x) = 3.50x - (1.25x + 25)
P(x) = 3.50x - 1.25x - 25
P(x) = 2.25x - 25
Hence, Marie's Profit would be P(x) = 2.25x - 25.
