First, we have the flat fee or admission fee. This means that you will pay $25 before you go on any rides at the amusement park.
Then, we have 4x.
The 4 represents the price of the ride. The reason we put x next to the 4 is because the x represents the number of times you will go on a roller coaster.
So now, we have 25 + 4x.
The reason we're adding is because we're trying to see how many rides we can go on with the amount of money we have saved up.
Now, the problem says we have $65 to spend.
This means that you can't spend more $65 but you can spend $65 exactly.
So, we will use the ≤ symbol meaning that you can spend less than $65 or $65 but no more than $65 or else you're going over your budget.
So we have 25 + 4x ≤ 65.
