What is the constant of proportionality in the equation 6y=3x6y=3x6, y, equals, 3, x?

if x = 1, then the answer is 3.5

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
