First, we can set up a system of equations to represent the total cost for each company:

Let x be the number of balloons ordered.

For Balloon Express:
2x + 10 = total cost

For Balloon Mania:
1.50x + 20 = total cost

Given that the O’Donnells plan to order 30 balloons:
2(30) + 10 = 60 + 10 = $70 for Balloon Express
1.50(30) + 20 = 45 + 20 = $65 for Balloon Mania

Therefore, the O’Donnells should choose Balloon Mania and will save $5.
