Best ResponseYou've already chosen the best response.1x = fixed fee y = hourly rate x + 3y = 97  multiply by 1 x + 7y = 205  x  3y = 97 (result of multiplying by 1) x + 7y = 205 add 4y = 108 y = 27 x + 3y = 97 x + 3(27) = 97 x + 81 = 97 x = 97  81 x = 16 check... x + 7y = 205 16 + 7(27) = 205 16 + 189 = 205 205 = 205 (correct) check.. x + 10y = 286 16 + 10(27) = 286 16 + 270 = 286 286 = 286 (correct) so the standard fee (x) = 16 and the hourly rate (y) = 27
