Let's represent the number of balloons the O'Donnells order as "x".
According to the problem, Balloon Express charges $2 per balloon and $10 for delivery. The total cost from Balloon Express would be 2x + 10.
On the other hand, Balloon Mania charges $1.50 per balloon and $20 for delivery. The total cost from Balloon Mania would be 1.50x + 20.
We know that the O'Donnells plan to order 30 balloons, so we can plug in x = 30 into the expressions for both companies:
Balloon Express: 2(30) + 10 = 60 + 10 = $70
Balloon Mania: 1.50(30) + 20 = 45 + 20 = $65
Therefore, the O'Donnells should choose Balloon Mania, and they will save $5 compared to Balloon Express.
The correct answer is A. Balloon Mania; $5.
