The price of the chairs and the quantity that maximizes profit is to sell 45 chairs at $75 each.
<h3><u>Profit</u></h3>
Given that a furniture store can sell 40 chairs per week at a price of $80 each, and the manager estimates that for each and $5 price reduction, she can sell five more chairs per week, and the chairs cost the store $30 each, to determine the price of the chairs and the quantity that maximize profit, the following calculation must be made:
- 40 x (80-30) = 2000
- 45 x (75-30) = 2025
- 50 x (70-30) = 2000
- 55 x (65-30) = 1925
Therefore, the price of the chairs and the quantity that maximizes profit is to sell 45 chairs at $75 each.

What would you need to know to find an unknown length?
For this case you need to know three measurements.
Two measures of the triangle that is similar and a measure of the original triangle.
Thus, the fourth measure is what will be the unknown side and is the one that we must find.
How would you find that unknown length?
Let:
a, b, c: known sides
x: unknown side
By similarity of triangles we have:
x / a = b / c
From here, we clear the value of the unknown side
Answer:
(Choice C) C Replace one equation with a multiple of itself
Step-by-step explanation:
Since system A has the equations
-3x + 12y = 15 and 7x - 10y = -2 and,
system B has the equations
-x + 4y = 5 and 7x - 10 y = -2.
To get system B from system A, we notice that equation -x + 4y = 5 is a multiple of -3x + 12y = 15 ⇒ 3(-x + 4y = 5) = (-3x + 12y = 15).
So, (-x + 4y = 5) = (1/3) × (-3x + 12y = 15)
So, we replace the first equation in system B by 1/3 the first equation in system A to obtain the first equation in system B.
So, choice C is the answer.
We replace one equation with a multiple of itself.
