The altitude of a plane is 1600ft. what must be the altitude of a submarine so that the sum of their altitudes is 0.

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

150.6

all i did was i multiplied 5.02 by 30
