There used to be a program in the Salt Lake valley where the electric company would pay customers who installed solar panels and contributed electricity to the grid A homeowner installed a solar panel system and made a contract with Rocky Mountain Power to sell them electricity Create a model which shows the cost of the system to the homeowner over time Here is information to use in this model This Salt Lake area gets an average of 8 hours of sunlight each day The system consists of 29 panels that each produce 380 Watts of power for each hour of sunlight 380 Watts 0 38 kilowatts The cost of the system was 21 200 Y The homeowner uses an average of 20 kWh each day for their home The rest they sell to Rocky Mountain Power at a rate of 0 13 for each kWh kilowatt hour a Find a linear equation that gives the total cost y of the panels after x days of use Enter the equation in slope intercept form y mx b You may write the slope as a decimal OR an unsimplified expression Recommendation Use the given information to determine how much the homeowner receives from Rocky Mountain Power each day Negating this will give you the slope b In how many days will the payments from Rocky Mountain Power pay for the system Round UP to the nearest day c In how many years will the payments from Rocky Mountain Power pay for the system Round UP to the nearest year Use 365 days 1 year
