Answer:
3.75%
Step-by-step explanation:
Kindly find attached the solution.
-6.9x - 7.8y = 71.76
to find the y int, sub in 0 for x and solve for y
-6.9(0) - 7.8y = 71.76
-7.8y = 71.76
y = 71.76/-7.8
y = -9.2...so the y int is (0,-9.2)
to find the x int, sub in 0 for y and solve for x
-6.9x - 7.8y = 71.76
-6.9x - 7.8(0) = 71.76
-6.9x = 71.76
x = 71.76 / -6.9
x = -10.4....so ur x int is (10.4,0)
We are given a relationship between the sides of a rectangle, that is, the length of one of its sides is 5 less two times its width, and we are asked to find an expression for the area. Let's remember that the area of a rectangle is equal to the product of the length of its side by its width. Let "w" be the length of the rectangle and "L" its lenght, then the area is given by the following formula:
We can use the relationship given in the problem, that is, its length being five less two times its width, that is:
Replacing in the formula for the area we get:
Now we use the distributive law:
Answer:
$117
Step-by-step explanation:
Given that:
They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each
Marginal Profit = Marginal Revenue – Marginal Cost.
Marginal Profit = $222 - $105
Marginal Profit = $117
the marginal profit for a single elementary statistics book $117
For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each
