PLEASE HELP ME ILL MARK BRAINLIEST

Answer:
a. R(t) = 2t - 500
b. D(t) = 400 + 10t
c. T(t) = 400 + 10t + 2t -500
Step-by-step explanation:
donations: $400; every person costs: $10; raffle ticket: $2; winner: $500
a. R(t) = 2t - 500
2t is the raffle tickets. t represents each person. -500 represents the money that the school loses for giving away the money to the winner.
b. D(t) = 400 + 10t
400 is the pre-donation that they had. 10t is the fee for entering the dinner per person. t represents each person.
c. T(t) represents all the money the school will gain (and lose) from the fundraiser. This stands to reason that T(t) is a combination of R(t) and D(t) since R(t) is the raffle and D(t) is the donations and dinner.
T(t) = 400 + 10t + 2t -500
Hope this helps!
