Let's represent the total cost for Balloon Express as $2x + 10 and the total cost for Balloon Mania as $1.50x + 20, where x is the number of balloons ordered (30 in this case).
Now we can set up a system of equations:
2x + 10 = total cost for Balloon Express
1.50x + 20 = total cost for Balloon Mania
Substitute x = 30 into the equations:
2(30) + 10 = $70 for Balloon Express
1.50(30) + 20 = $65 for Balloon Mania
Therefore, the O'Donnells should choose Balloon Mania and save $5.
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)
