A computer technician charges a flat base fee plus an hourly rate for all repairs. last year, she used the formula y = 18 x 22 to determine the cost in dollars, y, of a repair that required x hours of work. if she doubles her base fee this year, what equation should she use to determine the new cost of an x-hour repair? y = 18 x 44 y = 36 x 22 y = 36 x 44 2 y = 18 x 22
