Let's denote the number of balloons ordered as "x".
For Balloon Express, the cost equation is:
Cost of balloons = 2x
Delivery cost = 10
Total cost = 2x + 10
For Balloon Mania, the cost equation is:
Cost of balloons = 1.50x
Delivery cost = 20
Total cost = 1.50x + 20
Since the O'Donnells plan to order 30 balloons, we can substitute x = 30 into the cost equations:
For Balloon Express: Total cost = 2(30) + 10 = 60 + 10 = $70
For Balloon Mania: Total cost = 1.50(30) + 20 = 45 + 20 = $65
Therefore, the O'Donnells should choose Balloon Mania and they will save $70 - $65 = $5.
olve 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 Mania; $25 Balloon Mania; $25 Balloon Mania; $5 Balloon Mania; $5 Balloon Express; $5 Balloon Express; $5 Balloon Express; $25 Balloon Express; $25
