Question

Solve this real-world problem using a system of equations. The O'Donnells are having a birthday party for their son, and they plan to have a clown bring balloons to the party. Balloon Express charges $2 per balloon and $10 for delivery. Balloon Mania charges $1.50 per balloon and $20 for delivery If the O'Donnells plan to order 30 balloons, which company should they choose, and how much will they save? (1 point)

Balloon Express, $25

Balloon Express, $5

Balloon Mania, $5

Balloon Mania: $25

Answer 1

Let x be the number of balloons ordered and y be the total cost.

For Balloon Express:
2x + 10 = y

For Balloon Mania:
1.5x + 20 = y

Since the O'Donnells plan to order 30 balloons:
2(30) + 10 = 70 for Balloon Express
1.5(30) + 20 = 65 for Balloon Mania

Therefore, the O'Donnells should choose Balloon Mania which is $5 cheaper.
