Let's represent the number of balloons as "b" and the cost of delivery as "d".
For Balloon Express, the cost equation would be:
Cost of balloons = 2b
Cost of delivery = 10
Total cost = 2b + 10
For Balloon Mania, the cost equation would be:
Cost of balloons = 1.5b
Cost of delivery = 20
Total cost = 1.5b + 20
Now, we need to find the cost for 30 balloons for each company and compare them.
For Balloon Express:
Total cost = 2(30) + 10
Total cost = 60 + 10
Total cost = 70
For Balloon Mania:
Total cost = 1.5(30) + 20
Total cost = 45 + 20
Total cost = 65
The O'Donnells should choose Balloon Mania since they will save $5 compared to Balloon Express.
Therefore, the correct answer is:
D. Balloon Express; $5
