Given :
Ms. Liu has $60 to buy candy and soda at the movies theatre for her family.
Candy cost $6 per box and soda cost $4 per cup.
To Find :
Write an algebraic expression that can be used to find the amount of money ms. Liu will have left if she buys a number of boxes of candy (c) and cups of soda (s).
Solution :
Let, number of candy and soda are c and s.
So, their price is :
Price = 6c + 4s
Amount left = 60 - ( 6c + 4s )
Amount left = 60 - 6c -4s
Hence, this is the required solution.
