A School Holds a Fundraising Event $\$ 10$ For Dinner, Plus 50\$ for Each Raffle Ticket

A school holds a fundraising event. Attendees are charged $\$ 10$ for dinner, plus 50\$ for each raffle ticket. Create a function $\mathrm{f}(\mathrm{x})$ for the amount that a person pays if she eats dinner and purchases $\mathrm{x}$ raffle tickets. Use the function $\mathrm{f}(\mathrm{x})$ to determine how much a person pays if she eats dinner and plays 25 games.

A) $f(x) =50 x+10 ; \$ 1260.00$
B) $f(x) =0.5 x+10 ; \$ 22.50$
C) $f(x) =10 x+0.5 ; \$ 250.50$
D) $f(x) =0.5 x ; \$ 12.50$
