what is the function rule for the following situation? Res paid $20 for a membership to the pool and pays $3.00 each time he goes to the pool.
The function rule that represents the total cost (C) that Res pays to go to the pool x times is:
C(x) = 20 + 3x
Where x is the number of times Res goes to the pool and C(x) is the total cost he pays.

the answer is c
To find the function rule for this situation, we need to identify the relationship between the variables involved. In this case, we have two variables: the number of times Res goes to the pool (let's call it "x") and the total cost (let's call it "y").
Based on the information given, we know that Res pays $20 for the membership. This $20 is a fixed cost regardless of how many times Res goes to the pool. Therefore, the function rule starts with adding this fixed cost:
y = 20
Next, we know that Res pays an additional $3.00 each time he goes to the pool. Since the number of times Res goes to the pool is represented by the variable "x," we can express the additional cost as 3 times the value of "x":
y = 3x
Combining both parts, the function rule for this situation is:
y = 20 + 3x
Therefore, the total cost (y) is equal to $20 plus $3.00 multiplied by the number of times (x) Res goes to the pool.
