Question

Can you show the steps in how to solve it

Answer 1

To break even, the equations must satisfy that

`C(x)=R(x)\text{.}`

Substituting the explicit form of the equations, we get:

`50x+1600=66x\text{.}`

Subtracting 50x, we get:

`\begin{gathered} 50x+1600-50x=66x-50x, \\ 1600=16x\text{.} \end{gathered}`

Dividing by 16, we get:

`\begin{gathered} x=(1600)/(16), \\ x=100. \end{gathered}`

Answer:

`100\text{ units.}`
