Answer provided by our tutors
let
p = the cost of one large popcorn
d = the cost of one drink
a large popcorn and two drinks, their total is $9.00
p + 2d = 9
5 teenagers go to the movies and buy 2 large popcorns and 5 drinks, their total is $20.50.
2p + 5d = 20.50
by solving the system of equations
p + 2d = 9
2p + 5d = 20.50
we find
p = $5
d = $2.5
