Balloon Mania; $5
Let x be the number of balloons ordered and y be the total cost.
For Balloon Express: y = 2x + 10
For Balloon Mania: y = 1.50x + 20
Given that x = 30, we can find the total cost for each company:
For Balloon Express: y = 2(30) + 10 = $70
For Balloon Mania: y = 1.50(30) + 20 = $65
Therefore, the O'Donnells should choose Balloon Mania as it is cheaper by $5.
