Answer

-136

Step-by-step explanation:

The equation would be ½n-3=71. You add 3 to -71 and get -68. then you multiply by 2 and get -136

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

f(x)=4
