Pepperoni- 1 pizza is 15$

Cheese- 1 pizza is 10$

Total sold- 64 pizzas

15p+10c=$$

P+C=64

-15p-15c=-960

-5c=??

we dont know how many pizzas are sold for each if you did know I could solve

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
