Answer:
B. F:S = 17 to 19; S:F = 19 to 17
Step-by-step explanation:
Put the corresponding numbers in the corresponding parts of the ratio you want to write:
freshmen to sophomores (F:S)
17 to 19
___
sophomores to freshmen (S:F)
19 to 17
These pairs of numbers match choice B.
Y = total amount of money spent
x = cost of one drink
So our expression is:
4x + 12.75
4x stands for 4 drinks times x price of one drink
The 12.75 is a one time fee for the pizza, since Kiyo isn't buying multiple pizzas.
The problem also asks us to find the total price, so we write an equation:

We insert what x is which in this case is $3

Order of Operations tells us to multiply first:

Now add your values:

Therefore, Kiyo spent a total amount of 24.75 at Paola's pizza.
Let's check our problem just in case:

Since we now know what y is equal to, we can plug that into our original equation and check just to verify
We should subtract 12. on both sides of the equation because of inverse operations:

We are left with:

We divide:

Our result is:

Which checks out because each drink was in fact, $3 dollars as stated in the word problem. Hope that was thorough enough.
