Solve the problem.The cost of owning a home includes both fixed costs and variable utility costs. Assume that it costs $3171 per month for mortgage and insurance payments and it costs an average of $2.20 per unit for natural gas, electricity, and water usage. (i) Determine a linear function that computes the annual cost of owning this home if x utility units are used. (ii) What does the y-intercept on the graph of the function represent?
A. y = -2.20x + 3171; y-intercept, 3171, represents the minimum cost of owning the home without spending anything on utilities. B. y = 2.20x + 3171; y-intercept, 3171, represents the minimum cost of owning the home without spending anything on utilities. C. y = 2.20x + 38,052; y-intercept, 38,052, represents the minimum cost of owning the home for 12 months without spending anything on utilities. D. y = -2.20x + 38,052; y-intercept, 38,052, represents the minimum cost of owning the home for 12 months without spending anything on utilities.
