Answer:
There were 25 pizzas made last week.
Step-by-step explanation:
It is given that 64% of the pizzas had extra cheese and 16 pizzas had extra cheese. So it means that 64% is equals to 16 pizzas. In order to find how many pizzas were made, you have to find the remaining percentage of pizzas without extra cheese by subtracting 64% from 100% :
100 - 64 = 36 % of pizzas without extra cheese
64 % = 16 pizzas
1 % = 1/4 pizza
36 % = 9 pizzas
We have found out that 9 pizzas were made without extra cheese. The total pizzas were made last week is 25 pizzas (including extra cheese and no extra cheese) :
Total = Extra Cheese + No extra cheese
= 16 + 9
= 25 pizzas
