Solve the problem.The cost of owning a home includes both fixed costs and variable utility costs. Assume that it costs $2061 per month for mortgage and insurance payments and it costs an average of $3.23 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 = -3.23x + 2061; y-intercept, 2061, represents the minimum cost of owning the home without spending anything on utilities.
B. y = -3.23x + 24,732; y-intercept, 24,732, represents the minimum cost of owning the home for 12 months without spending anything on utilities.
C. y = 3.23x + 2061; y-intercept, 2061, represents the minimum cost of owning the home without spending anything on utilities.
D. y = 3.23x + 24,732; y-intercept, 24,732, represents the minimum cost of owning the home for 12 months without spending anything on utilities.
