Answer QUICK Par T Catering calculates its bill, P, for a brunch event using the equation P = 15g + 125, where g is the number of guests dining. Celebrations Catering calculates its bill for a brunch event as a flat fee plus a charge of $20 per guest dining.

If Par T and Celebrations charge the same total amount for a brunch serving 10 people, is it possible to determine the amount that Celebrations would charge for a brunch serving 25 people? Explain why or why not, showing how to derive the charge if it is possible.
