Question

Valeria opened a business making masks. She pays $5.00 for the materials to make the mask and sells it to customers for $8.00. How much profit would Valeria make if she sold 15 masks?

a) $45.00
b) $30.00
c) $15.00
d) $60.00

Answer 1

Valeria earns a profit of $3.00 per mask by subtracting the cost from the selling price. The total profit for selling 15 masks is calculated by multiplying the profit per mask by the number of masks, resulting in a total profit of $45.00.

Step-by-step explanation:

The student asked how much profit Valeria would make if she sold 15 masks, given that she pays $5.00 for materials for each mask and sells each for $8.00. To calculate the profit per mask, we subtract the cost from the selling price: $8.00 - $5.00 = $3.00 profit per mask. To find the total profit for 15 masks, we multiply the profit per mask by the number of masks: $3.00 × 15 = $45.00.

Total revenues in this case would be the selling price multiplied by the number of units sold, which is:

• 15 masks × $8.00/mask = $120.00

Total costs would be the cost of materials multiplied by the number of units produced, which is:

• 15 masks × $5.00/mask = $75.00

To determine the total profit, we subtract total costs from total revenues, hence:

• $120.00 (revenues) - $75.00 (costs) = $45.00 (profit)

Therefore, the correct answer is a) $45.00.
