Answer:

10 tickets

Step-by-step explanation:

There is always a fixed cost of 8.75 whenever you want to avail the service.

So 8.75 is fixed

Now, each ticket, t, costs 18.50, so it would cost Sandra 18.5*t to buy t tickets. Of course, this has to be LESS THAN or EQUAL TO 200. We can now write and inequality of this form shown below (remember 8.75 is fixed):

[tex]8.75+18.50t  \leq 200[/tex]

Let's solve this and find the max number of tickets Sandra can buy:

[tex]8.75+18.50t  \leq 200\\18.50t \leq 200 - 8.75\\18.50t \leq 191.25\\t \leq \frac{191.25}{18.50}\\t \leq 10.34[/tex]

You can't buy fractional amount, so Sandra can basically buy 10 tickets
