140x = 8400

\frac{140x}{140}  =  \frac{8400}{140}

x = 60

Our answer is 60.

Good luck.

In this activity, you will create quadratic inequalities in one variable and use them to solve problems. Read this scenario, and
AnnyKZ [126]

Answer:

  A: cost = 10+x; customers = 16-2x

  B: -2x² -4x +160 ≥ 130

Step-by-step explanation:

In these price and revenue optimization problems, the relation between price and sales is given in the problem statement. After that is translated to math terms, the revenue as the product of price and sales can be determined.

<h3>Part A</h3>

The variable x is defined as the number of $1 increases from a price of $10. That means ...

  Cost = 10 +x

For each $1 increase, the number of customers decreases by 2 from a starting value of 16:

  Customers = 16 -2x

__

<h3>Part B</h3>

The problem statement tells you the revenue (per hour) is the product of cost and number of customers. The owner wants this to be at least 130:

  (Cost)(Customers) ≥ 130

  (10 +x)(16 -2x) ≥ 130

  160 -20x +16x -2x² ≥ 130 . . . . eliminate parentheses

  -2x² -4x +160 ≥ 130 . . . . . . . . . put in required standard form

_____

<em>Additional comment</em>

The attached graph shows the solution to this quadratic inequality is ...

  -5 ≤ x ≤ 3

and that revenue can be increased by $2 per hour by decreasing cost $1 (x=-1).

The midsegment through the legs of an isosceles triangle is 4 in. Find the sides of the triangle if its perimeter is 20 in. 75 p
Pani-rosa [81]

The midsegment is half the length of the base. So the base = 2*4 = 8 in.

Since it is an isosceles triangle, the other two sides are equal in length.

Perimeter = sum of two equal sides + base = 20 in.

2x equal side + 8 = 20

equal side = 12/2 = 6

Each of the equal sides = 6"
