For this case the first thing we should do is find the percentage of people surveyed who said that pizza pizza was their favorite type of pizza.
We have then:

We are now looking for 52.5% of 1600 people.
For this, we make the following rule of three:
1600 ----------> 100%
x ---------------> 52.5%
Clearing the value of x we have:
Answer:

Step-by-step explanation:
It seems like the rule of this sequence is to add 5 (since 2 + 5 = 7 and 7 + 5 = 12). We already are given that we have 2 2-digit numbers (12 and 17) so let's see if there are any more. The sequence continues to 22, 27, 32, 37, 42, 47, ..., 92, 97. We need to count how many numbers are in the list 12, 17 ... 92, 97. To do this, let's add 3 to every term in the list to get 15, 20, ... 95, 100. Since the list is now full of multiples of 5 we can divide the list by 5 to get 3, 4, ... 19, 20 and then subtract 2 to get 1, 2, ... 17, 18 which means that there are 18 2-digit numbers.
