Question

The number of pizzas is in a proportional relationship to the weight of the shredded cheese toppings. When​ shredded, a 30​-lb block of cheese is enough to make 127.5 large pizzas. Find the constant of proportionality. Explain how you can use a constant of proportionality to find how much cheese is on one slice of pizza if there are 8 slices per pizza.

Answer 1

30......................127,5
1.........................x

30x = 127,5
x = 127,5/30
x = 4,25 

1 libra = 4,25 pizzas
4,25 pizzas.............1 libra
1 pizza.....................y

4,25y = 1
y = 1/4,25
y = 0,2353 libra (1 pizza)
1/8 de pizza = 0,2353/8 = 0,0294
