Steve is a painter. he can paint a house in 20 hours. it takes his assistant 30 hours to paint a house. how long, in hours, would it take them to paint a house working together?

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

x coordinate is none
