Lombardi's pizza sells one 18-inch cheese pizza or two 12-inch cheese pizzas for $12.99. determine which size gives more pizza. (a=πr^2)

The 2 12 inch cheese pizzas gives more pizza.

Step-by-step explanation:

12 inch pizzas

A = π 6^2

A = 113.097 inches^2

18 Inch pizza

A = π x 9^2

A = 31 x π

A = 97.3894

(r=1/2 off the diameter, so 12/0.5=6)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
