The flat fee would be $3 and having each ticket cost $18. You would need to set the data up as (5, 93) and (3, 57) and then using them to find the change in Y over the change in X. What I did was 93 - 57/ 5 - 3 to equal 36/2 or 18. Then you would need to substitute the information into the equation Y= mX + B. You can pick either of the data points and fill them in accordingly as I did
57=18(3)+B. After multiplying 18 and 3, you get 54, which you subtract on both sides to get B, or the flat fee to be $3. Hope this helps.
