Solve this real-world problem using a system of equations. The O’Donnells are having a birthday party for their son, and they plan to have a clown bring balloons to the party. Balloon Express charges $2 per balloon and $10 for delivery. Balloon Mania charges $1.50 per balloon and $20 for delivery. If the O’Donnells plan to order 30 balloons, which company should they choose, and how much will they save?(1 point)
Balloon Express; $5
Balloon Express; $5
Balloon Mania; $25
Balloon Mania; $25
Balloon Express; $25
Balloon Express; $25
Balloon Mania; $5
Let's use the equation:
A = number of balloons
D = delivery fee
C = cost
For Balloon Express:
E1: C = 2A + 10
For Balloon Mania:
E2: C = 1.50A + 20
Given that the O'Donnells plan to order 30 balloons:
A = 30
Plug A = 30 into the equations:
E1: C = 2(30) + 10
C = 60 + 10
C = 70
E2: C = 1.50(30) + 20
C = 45 + 20
C = 65
Therefore, the O'Donnells should choose Balloon Mania as they will save $5 by choosing them.
