problem_activity: Several campuses are holding fundraisers and tallied the amount of tickets they sold, the amount of money they raised, and any one-time donations.
The prediction for how each campus would price the tickets, plus one-time donations was:
$${y=2.5x + 50}$$
Part A
Which campuses, based on the amount of tickets sold and the total amount raised, appear to have followed the model prediction?
[IMG]
Part B
Central East and Central West forgot to send in their total amounts of money raised. The director used the prediction equation and his best guess of a sale of 25 tickets and 42 tickets, respectively. How much money did the director predict Central East and Central West raised?
