A candy company sells cases of chocolate bars the company has cost of 30000 and each case of chocolate bars cost an additional 5 to make the company sells each class=

Respuesta :

We have two functions:

- The cost function C(x) that can be described as the fixed cost ($30,000) plus the variable cost (the unit variable cost per unit times the units, 5x)

[tex]C(x)=30000+5x[/tex]

- The revenue function R(x) which is the price times the number of units.

[tex]R(x)=10x[/tex]

We have to find x for which cost and revenue are the same.

This can be expressed mathematically as C(x) = R(x).

We then can solve it as:

[tex]\begin{gathered} C(x)=R(x) \\ 30000+5x=10x \\ 30000=10x-5x \\ 30000=5x \\ x=\frac{30000}{5} \\ x=6000 \end{gathered}[/tex]

This means that the company has to sell x = 6000 chocolate bars to break even (costs = revenue).

Answer: 6000 chocolate bars.
