Hello! I won't give you the answer but I'll show you an example to a similar question like that!
Okay, so what if: a person can pay $6 for a membership to the art museum and then go to the museum for just $1 per visit. what is the maximum number of the art museum can make for a total cost of $18?
An easy way to solve this is to make an equation.
Let's call the number of times we can visit "x".
So, we pay $6 off the bat, and then pay $1 per visit after.
6+1x
That's the cost associated with visiting "x" number of times, now, we need to know how many times we can visit for 18, so we equate the expression to 18.
6+x=18
x=12
We can visit 12 times.
I hope this helps and that now you know the problem is supposed to be solved!
See ya later, pal!
