A sundae with 1 topping is $0.99, with 4 toppings is $1.74, and with 7 toppings is $2.49. Which equation represents the cost of the sundae, c, given number of toppings, r?

Evaluate the function , when d = {9, 15, 30}. r = {5, 7, 12} r = {6, 10, 15} r = {6, 10, 20} r = {5, 12, 20}

Arational number that is equivalent to -20/4?
