Final answer:
The profit equation for Gary's publishing company should show the total revenue from selling x books subtracted by the explicit costs. Since explicit costs are subtracted from revenue to calculate profit, the correct equation would include a positive term for the revenue per book and a negative term for the costs.
Step-by-step explanation:
To find the equation that represents the profit earned by selling x books for Gary's publishing company, we need to understand the structure of a profit equation. Profit is calculated by subtracting costs from total revenue. In this case, we have the selling price of one book (which, when multiplied by the quantity x, gives us total revenues) and the explicit costs associated with producing a certain number of books.
Given the options provided:
A) Profit = $15x - $1,050
B) Profit = $35x - $1,050
C) Profit = $15x + $1,050
D) Profit = $35x + $15
it's clear that the equation should represent a scenario where costs are subtracted from the total revenues to yield profit. The term that subtracts a certain dollar amount—$1,050 in this case—would likely represent the explicit costs or fixed costs of publishing.
Therefore, the correct profit equation would subtract $1,050 from the total revenue of selling x books. We are looking for an equation with a positive revenue term and a negative cost term.
