Dion owns a delivery service. He charges his customers $15.00 for each delivery. His expenses include $7000 for the motorcycle he drives and $0.42 for gasoline per trip. Which equation could Dion use to calculate his profit p for d deliveries

p = $15d - (7,000 + 0.84d)

Step-by-step explanation:

In this question, we are asked to given an equation that will represent the profit Dion makes when he has made a total of d deliveries.

We proceed as follows:

To calculate the profit, we need to subtract the cost price from the selling price.

Let's start with the cost price. This refers to the total amount of money that is used to prepare the goods for sales and also spent on that cause. He charges $0.42 for gasoline per trip. This means it is a total of $0.84 for each delivery. This is because two trips will make a delivery. Total number of money spent on gasoline on deliveries is thus 0.84 * d = 0.84d. Now, we add the cost of Motorcycle he rides to be $7,000. The total money spent is thus $7000 + $0.84d

His selling price is simply the number of deliveries he has made multiplied by the amount of money he charges per trip. This is same as 15 * d = $15d

Profit is thus; p = $15d - (7,000 + 0.84d)
