Question

At pizza express it takes 6 cups of cheese to make 15 pizzas. At perfect pizza it takes 4 cups of cheese to make 6 pizzas. If the number of pizzas,y,is proportional to the cups of cheese,x, which pizza place has a larger constant of proportionality?

Answer 1

Pizza Express has a larger constant of proportionality than Perfect Pizzas because 1.6 > 1.5

15/6        6/4

  Simplify

5/3    >    3/2

PE: 5/3 or 1.6

PP: 3/2 or 1.5

I had this on my math test
