Final answer:

To find the total number of pizzas made last week, set up a proportion using the information given: 0.09/x = 27/x. Solve for x to find that 300 pizzas were made last week.

Step-by-step explanation:

To find the total number of pizzas made last week, we can set up a proportion using the information given. Let x represent the total number of pizzas:

9% (or 0.09) of the pizzas had extra cheese, so we can set up the proportion 0.09/x = 27/x. Cross-multiplying, we get 0.09x = 27, and dividing both sides by 0.09, we find that x = 300.

Therefore, 300 pizzas in total were made last week.

At Pizza Pi, the number of Pizzas that had extra cheese last week = 27
The percentage of Pizzas that had extra cheese last week = 9%
Let us assume that the number of Pizzas made last week = X
Then
we can write the equation as,
9X/100 = 27
9X = (27 * 100)
9X = 2700
X = 2700/9
= 300
Then it can be deducted that 300 pizzas were made last week .
