QUESTION: You see your friend staring at the starting screen of the Geogebra 3D Calculator. “What’s wrong,” you ask. “I don’t know where to begin. Can you help me?” Explain how you might begin to help your friend … what would you do first?

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

5x10^11 x 65

325 x 10^11

or

325,
