The sophomore class is planning to sell school mascot puppets to help cover the cost of a class trip. A local supplier will char

kifflom [539]

Answer:

755 or more

Step-by-step explanation:

The profit is the difference between revenue and costs. We want the profit to be $2000 or more, and we have both fixed and variable costs.

Let x represent the number of puppets sold. Then the costs are ...

... 76.25 + 2.25x

The revenue is 5x.

The above-described relationship can then be written as

... 5x -(76.25 +2.25x) ≥ 2000

... 2.75x ≥ 2076.25 . . . . . add 76.25, collect terms

... x ≥ 2076.25/2.75 . . . . divide by the coefficient of x

... x ≥ 755

755 or more puppets must be sold to earn $2000 or more.

Can any one help me and work 2 or 3 of the problems for me to understand it

Alekssandra [29.7K]

To solve these problems you need to use the quadratic formula which is listed below.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

So, if you take #2.

The $x^{2}$ has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:

a = 1
b = -3
c = -3

Then you can plug all of these into the equation and simplify. Which gives you:

$\frac{3 -/+ \sqrt{21} }{2}$
