Chicago Pizza charges $10.49 for a medium 14" pepperoni pizza and NY Pizza charges $20.99 for an x-large 18" pepperoni pizza.
UNO [17]

Answer:

A; The cost is $0.07 per  inch^{2}

Step-by-step explanation:

In this question, we are asked to calculate the cost of the Chicago pizza per square inch rounded to the nearest cent.

Firstly, we will need to calculate the area occupied by the 14 inch medium pepperoni pizza made by Chicago pizza

Since the pizza is circular in shape, we use the formula for the area of a circle to calculate its area in square inch

Mathematically, the area of a circle is equal to πr^{2} . Here, our r is half the size of the pizza as the 14 inch represents the full length of the pizza across the center of the pizza = 7 inch

The area is thus = 22/7 × 7 × 7 = 154 inch^{2}

Now, since the full pizza costs $10.49, the cost of the pizza per  inch^{2} is 10.49/154 = 0.068 = $0.07 per  inch^{2}
