A rectangular parking lot is 253.5 feet long and 175.5 feet wide. A 55-gallon drum of asphalt sealer covers 4,000 square feet and costs $96.50. Find the cost to seal the parking lot. (Sealer can only be purchased in full drums.)

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
