Sidney Peters · Answer 1

Step-by-step explanation:

Let x represent the number of pounds of soap that she makes and eventually sells.

She intially spent $72 to purchase soap-making equipment, and the materials for each pound of soap cost $7. This means that the total cost of making x pounds of soap would be

7x + 72

Lisa sells the soap for $10 per pound. This means that her revenue for x pounds of soap would be

10 * x = 10x

If she eventually sells enough soap to cover the cost of the equipment, then

7x + 72 = 10x

10x - 7x = 72

3x = 72

x = 72/3 = 24

She would need to sell make and sell 24 soaps.

The cost would be

72 + 7 * 24 = $240

The total sales would be

10 * 24 = $240
