Answer:

Step-by-step explanation:
<h3>Derivative </h3>

Since, the derivative of e^x is e^x and e^(yx) is ye^(yx)
Let's make an equation where x is the number of gallons and y will be the overall price.
2.5x=y; since it is $2.52 PER gallon, you need to multiply the amount of gallons by the cost. In this case, it is 4.
2.5(4)=10
So, the price of 4 gallons is $10.
