To solve this problem using a system of equations, we can set up two equations representing the total cost for each company.
Let's assume the number of balloons ordered is x.
For Balloon Express, the total cost would be: 2x + 10 (2 dollars per balloon plus a 10-dollar delivery fee)
For Balloon Mania, the total cost would be: 1.5x + 20 (1.50 dollars per balloon plus a 20-dollar delivery fee)
Since the O'Donnells plan to order 30 balloons, we can substitute x = 30 into the equations:
For Balloon Express: Cost = 2(30) + 10 = 60 + 10 = 70 dollars
For Balloon Mania: Cost = 1.5(30) + 20 = 45 + 20 = 65 dollars
Therefore, they should choose Balloon Mania, and they will save:
70 - 65 = 5 dollars
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) Responses Balloon Express; $25 Balloon Express; $25 Balloon Mania; $25 Balloon Mania; $25 Balloon Express; $5 Balloon Express; $5 Balloon Mania; $5 Balloon Mania; $5
