Answer:
The bottle costs $1.10 and the cork costs $0.10.
Step-by-step explanation:
x = cost of the bottle in cents
y = cost of the cork in cents
x + y = 120
x = 2y + 90
Solve the system of equations with substitution or elimination. Using substitution:
2y + 90 + y = 120
3y + 90 = 120
3y = 30
y = 10
x = 110
The bottle costs $1.10 and the cork costs $0.10.
