Question

Answer 1

pedro must sell at least 2 chairs

Answer 2

Answer:

4 chairs.

Step-by-step explanation:

Let x represent number of chairs.

We have been given that Pedro charges $65 for a chair, so the revenues earned from selling x chairs would be $65x$.

We have been given that the materials for a chair cost $45 and there is a $75 dollar fee for a booth at the market. The total cost of making x chairs would be $45x+75$.

We know that to get a profit the revenues earned from selling x units must be greater than total cost of producing x units.

$65x>45x+75$

$65x-45x>45x-45x+75$

$20x>75$

$\frac{20x}{20}>\frac{75}{20}$

$x>3.75$

To make a profit Pedro must sell more than 3.75 chairs. The closest integer to 3.75 is 4, therefore, Pedro must sell 4 chairs to make a profit.
