What is the function rule for the following situation? Rex paid $20 for a membership to the pool and page three dollars each time he goes to the pool.

A.y=20x+3
B.20=3x+y
C.y=x+20
D.none of these

A. y=20x+3

the answer is c idk how but i took the same test and its c

To determine the function rule for this situation, we need to analyze the information and identify the pattern. We know that Rex pays $20 for a membership to the pool and an additional $3 each time he goes to the pool.

Let's break it down step by step:
- When Rex buys a membership, he pays a fixed amount of $20.
- Each time Rex goes to the pool, he pays an additional $3.

Based on this information, we can conclude that the function rule should have a constant term of $20 and a variable term of $3 multiplied by the number of times Rex goes to the pool (let's call it 'x').

The correct function rule for this situation is:
y = 20 + 3x

So, the answer is A. y = 20x + 3.

Again, the bot is wrong

He pays : $20 + 3(each visit)
looking for y = 3x + 20 , couldn't find it , so D, none....
