If a 10 pepperoni pizza from a pizza parlor costs $9.14,
a 12 pizza from the pizza parlor should cost $10.97.

compute square inches and extrapolate, or go hungry.

As someone who has actual bought pizza I'm going to assume that you are talking about a 10 inch vs 12 inch pizza. Where the size is the diameter of the pizza.
The area is proportional to the square of the diameter
therefor the price will also be proportional to the square of the diameter
p/9.14 = (12/10)²
p = (12/10)² * 9.14
p = 144 / 100 * 9.14
p = 13.1616

We know the price must be proportional to the area of pizza. Thus it is proportional to the square of the diameter. Let x be the price:
9.14/10² = x/12²
x = 12² * 9.14/10² = $13.16 <<<

The math concept here is equivalency. So it's just like 1/2 = X/4 and solving for X to make the two fractions equivalent. The only difference is that your numbers are different. You have 9.14/10 = X/12. Solve for X, which is your numerator and you'll have how much that 12 inch or slice pizza will cost. In other words, you're getting your cost per inch or slice and using this to get your answer.Source(s): I've taught math on the college and in the public schools. And have helped out lots of students with problems like this.

It’s 91.4¢ per pepperoni so 12 pepperoni pizza would cost $10.97.
