Let's solve this problem using a system of equations.
Let
x = number of balloons
y = cost for delivery
Based on the given information, we can set up the following equations:
For Balloon Express:
Cost = 2x + 10
For Balloon Mania:
Cost = 1.50x + 20
We know that the O'Donnells plan to order 30 balloons, so we can substitute x = 30 into both equations:
For Balloon Express:
Cost = 2(30) + 10
Cost = 60 + 10
Cost = 70
For Balloon Mania:
Cost = 1.50(30) + 20
Cost = 45 + 20
Cost = 65
Therefore, the O'Donnells should choose Balloon Mania as they will save $5 compared to Balloon Express. The correct answer is option C: $5 Balloon Mania; $25 Balloon Express.
