Provide an appropriate response.Suppose that you start a business manufacturing and selling computers, and it costs you $8151 to get started. You determine that each computer will cost $1118 to manufacture and you choose to sell each for $2139. Form a system from two equations, assuming 
that is, 
and then solve the system. Round to the nearest whole number.
A. y1 = 8151x + 1118 y2 = 2139x (0, 64,090) B. y1 = 1118x + 8151 y2 = 2139x; (6, 14,859) C. y1 = 1118x + 8151 y2 = 2139x; (8, 17,095) D. y1 = 8151x + 1118 y2 = 2139x; (0, 66,326)
