Answer provided by our tutors
let
x = the cost of the bottle
y = the cost of the juice
a full bottle of juice costs $2.00:
x + y = 2.00
the cost of the juice is $1.50 more than the cost of the bottle:
y = 1.50 + x
by solving the system of equations:
x + y = 2.00
y = 1.50 + x
we find:
x = $0.25
x = 25 cents
