You want to sell t-shirts for $12 a piece. It cost you $40 for supplies. Is the total profit proportional to the number of t-shirts you sell?
No, the total profit is not proportional to the number of t-shirts sold. The profit is the difference between the total revenue and the cost, which is given by the equation Profit = Revenue - Cost.
If 'x' is the number of t-shirts sold, then the revenue is given by Revenue = 12x. The cost is a fixed amount of $40.
Therefore, the profit equation becomes Profit = 12x - 40. Since there is a constant term (-40) in the equation, the profit is not directly proportional to the number of t-shirts sold.
