EC Math Propane Fill Options

For this project, you're going to investigate the costs to fill a 1,250 gallon propane tank to different levels.

Use the following table to determine propane costs based on the amount you will purchase.
The propane company gives a discount when you buy more.

100 - 500 gallons: $2.76/gallon
501-750 gallons: 5% discount
751-1000 gallons: 10% discount
Over 1000 gallons: 15% discount

You decide it's too expensive to fill up the tank the whole way, so you tell the company to only fill it 75% full.

You decide that's still too expensive, so you tell the company to only fill it 65% full.

If you only fill your 1,250 gallon tank 65% full, how many gallons of propane will you buy?
