You own and operate a gasoline station. You started your business on May 1. At your site you have one, and only one, 30,000-gallon tank for regular, unleaded, 87 octane gasoline. Your station sells only 87 octane gasoline.

On April 30, your tank is MT. That same day you take delivery of the following amounts of gasoline:

8200 gallons @ $1.88 per gallon

8000 gallons @ $1.97 per gallon

9200 gallons @ $2.10 per gallon

All prices include all taxes and delivery charges

You sold no gas on April 30; you opened business on May 1

Assume no losses due to leaking tanks, evaporation or theft

Sales for May 1 thru 31:

7100 gallons @ $2.249

8800 gallons @ $2.099

6600 gallons @ $2.149

You are to calculate:

A) Average cost per gallon of gas in inventory on April 30

B) Inventory, in gallons, at end of business on May 31

C) Average selling price per gallon for May

D) Gross margin $ for May (gross sales $ of gas minus cost).
