The cost of owning a home includes both fixed costs and variable utility costs. Assume that it costs $4,095.00 per month for mortgage and insurance payments and
it costs an average of $4.77 per unit for natural gas, electricity, and water usage. Determine a linear equation that computes the annual cost of owning this home if
x utility units are used.
A. $y = -4.77x + 49,140$
B. $y = 4.77x + 49,140$
C. $y = 4.77x + 4095$
D. $y = -4.77x + 4095$
