Answer:
See below. (C*a) + (P*b) = M
Step-by-step explanation:
amount of students = 45
amount of candy per student = 1
amount of popcorn per student = 1
Let "S" be the total amount of students
Let "C" be the total amount of candy
Let "P" be the total amount of popcorn
Let "T" be the total number of snacks
Let "a" be the price per candy
Let "b" be the price per popcorn
Let "M" be the total amount of money spent at the game
The price of the candy is unknown.
The price of the popcorn is unknown.
The total amount of money spent at the game is unknown.
(C*a) + (P*b) = M
