in a photograph alison stands next to her brother caleb. alison is 4 cm fall in the photograph. her actual height is 60 in. caleb is 3.2 cm tall in the photograph. what is his actual height?

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

they would have to work 32 hours.
