Papa Jhones sold 675 cheese and pepperoni pizzas last night. There were 4 times as many pepperoni pizzas as cheese. How many types of pizza was sold

Answer 1

Let's start by assigning each type of pizza a letter:

C = cheese pizzas

P = pepperoni pizzas

We know that Papa sold four times as many pepperoni pizzas as he sold cheese pizzas. So:

P = 4C

We also know that, altogether, Papa sold 675 pizzas. So:

P + C = 675

Since P = 4C, we can substitute:

4C + C = 675

5C = 675

C = 135

So Papa sold 135 cheese pizzas.

Well, if Papa sold four times as many pepperoni pizzas as he sold cheese pizzas, then he must have sold 4 x 135 = 540 pepperoni pizzas.

Do the number of cheese pizzas sold and the number of pepperoni pizzas sold add up to 675? Let's check:

P + C = 675

540 + 135 = 675.

Yes, we are right!
