Answer:

9 tickets

Step-by-step explanation:

Let x = the number of tickets

let y = the total she spends

So   y = 5 + 8 + 0.75x

If the max she can spend is 20, set y = 20 and solve for x:

5 + 8 + 0.75x = 20

13 + 0.75x = 20

0.75x = 20 - 13

0.75x = 7

x = 7 ÷ 0.75 = 9.333333333

Therefore, the max number of tickets that can be bough is 9
