    He charges $1.50 per delivery and then $2 per km he has to drive to get from his kitchen to the delivery address. Write an equation that can be used to calculate the delivery price and the distance between the kitchen and the delivery address. Use your equation to calculate the total cost to deliver to someone 2.4km away

    Let k be the number of kilometers between the kitchen and delivery address. Our Delivery equation D(k) is:
    D(k) = 2k + 1.50

    The problem wants to know D(2.4):
    D(2.4) = 2(2.4) + 1.50
    D(2.4) = 4.8 + 1.50
    D(2.4) = $6.30
