Basic Method:
Area to fertilize;
How many bags;
What cost for the needed fertilizer.

Area to cover: 80%2A20+%2A3%2A3 because you want as square feet.

Number of bags: 80%2A20%2A3%2A3%2A%281%2F100%29 because 1 bag covers 100 square feet.

Cost: 80%2A20%2A3%2A3%2A%281%2F100%29%2A7.50 dollars, using the bag price
