I am going to order groceries for making pumpkin pies. It costs $2.91 per pumpkin plus $14.62 for the delivery fee regardless of how many pumpkins I purchase. Let C(p)

be the cost of groceries where p is the number of pumpkins I am buying. An appropriate model is: a. C(p)=2.91p b. C(p)=14.62p+2.91 c. C(p)=(2.91+14.62)p d. C(p)=2.91p+14.62
