Solve the problem.The cost of owning a home includes both fixed costs and variable utility costs. Assume that it costs $2098 per month for mortgage and insurance payments and it costs an average of $2.87 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 = -2.87x + 2098; y-intercept, 2098, represents the minimum cost of owning the home without spending anything on utilities.
B. y = 2.87x + 2098; y-intercept, 2098, represents the minimum cost of owning the home without spending anything on utilities.
C. y = 2.87x + 25,176; y-intercept, 25,176, represents the minimum cost of owning the home for 12 months without spending anything on utilities.
D. y = -2.87x + 25,176; y-intercept, 25,176, represents the minimum cost of owning the home for 12 months without spending anything on utilities.
