Question

You sell face masks for $5 per mask. You invested $40 in materials to make the masks.Write a formula that gives the profit in dollars P=P(m) as a function of the number m of masksyou sell.

Answer 1

The profit is computed as:

Profit = total sales - total expenses

Calling m to the number of masks sold,

total sales = 5m

Total expenses are $40, then:

P(m) = 5m - 40
