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
x utility units are used
A.y=-4.77x+49,140
OB.y=4.77x+49,140
OC.y=4.77x+4095
OD.y=-4.77x+4095
