3. noah is to collect the entry fees at his school's sports game. student entry
costs $2.75 each and adult entry costs $5.25 each. at the end of the game, diego
collected $281.25.
select all equations that could represent the relationship between the number of
students, s, the number of adults, a, and the dollar amount received at the game.
a. 281.25 – 5.25a = 2.75s
b. a = 53.57 - 13: 25
c. 281.25 -5.25s = a
d. 281.25 +2.75a = s
e. 281.25 +5.25s = a

281.25-5.25a=2.75

step by step:

so you divide the total amount by two and you get 140.62

then you divide that by 5.25 and you get 26.78

plug that into a and you get 140.62

then you take the remainder which is 140.62 and you divide that by 2.75

which is 51.13 and that will be your number for s

and at the end you should get the remainder of 140.62

then you multiply 140.62 by 2 and you get were you started and thats how you check your answer
