Use a computer algebra system to graph the surface and locate any relative extrema and saddle points. (If an answer does not exist, enter DNE.) z = exy
relative minimum (x, y, z) =
relative maximum (x, y, z) =
saddle point (x, y, z) =

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
