3. seven

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

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 +

inequality is

10 < 0.55x +

1.75

x > 2
