Answer: hello your question is poorly written below is the complete question
Suppose your total benefit from eating slices of pizza​ (value in​ dollars) is 12x - x^2​, where x is the number of slices of pizza. Pizza is sold by the slice and costs ​$2 per​ slice, and so the total cost of pizza is 2x. Using optimization in​ levels, what is the optimal amount of pizza for you to​ eat?
answer:
5 slices
Explanation:
Total Benefit/profit per slice = 12x - x^2
number of slices = x
unit cost of pizza ( per slice ) = $2
Total cost of pizza = $2 * x = 2x
Determine the optimal amount of pizza to be eaten
using optimization process to determine the Maxima
F ≡ ( 12x - x^2 ) - ( 2x )
= 10x - x^2
F' = 10 - 2x =0
hence x = 10 /2 = 5 slices
