Question

A. Write an expression that represents the total cost of large pizza. let t = # of toppings.

b. Brust orders an “everything” pizza with 8 toppings. use your expression to find the total cost of the pizza.

c. Kelly and Bean show up and order 4 identical pizzas. write an expression that represents the total cost for the 4 pizzas. (each pizza would have the same # of toppings.)

d. Kelly and Bean order sardines and pineapple on the 4 pizzas. use your expression from (c) to find the total cost of the 4 pizzas.

Answer 1

a). Total cost of one pizza = 14.99 + 1.99t

b). $30.91

c). Cost of 4 pizza = 59.96 + 7.96t

d). Total cost of 4 pizza with 2 toppings = $75.88

Explanation:

a). Cost of the large pizza = $14.99

Each topping of the pizza is $1.99 extra.

If total number of layers of the toppings = t

Total cost of one pizza = 14.99 + 1.99t

b). Brust orders a pizza with number of toppings = 8

From the given expression,

Total cost of pizza = 14.99 + 1.99(8)

= 14.99 + 15.92

= $30.91

c). Kelly and Bean ordered number of identical pizzas = 4

Expression that represents the cost of 4 pizzas = 4(14.99 + 1.99t)

= 59.96 + 7.96t

d). Kelly and Bean order 4 pizzas with sardines and pineapple. That means 2 toppings on one pizza.

Cost of 4 pizza with toppings = 59.96 + 7.96×2

= $75.88
