Daija is looking to fertilize her 24,000 square foot lawn. Super Lawn fertilizer costs $18.49 and covers 6,000 square feet. Quick Fertilizer costs $23.99 and covers 8,000 square feet. Part A
Which fertilizer would be cheaper for Daija to purchase to fertilize her entire lawn? Show your work or explain your answer.

The cheapest fertilizer would be Super Lawn fertilizer because if you multiply the individual cost by her entire lawn and then divide it by the cost of one square feet, you will notice that she pays less with the Super Lawn.

Part B:
Daija has a 15% off coupon on the cheaper fertilizer. Excluding sales tax, what is the new cost of the fertilizer? Round to the nearest cent.
