Which expression results the smallest difference? A.12.5 - 3.1
B.12.5 - 0.31
C.12.5 - 0.031
D.12.5 - 0.0031

A. 12.5 - 3.1

Step-by-step explanation:

A. 12.5 - 3.1 = 9.4

B. 12.5 - 0.31 = 12.19

C. 12.5 - 0.031 = 12.469

D. 12.5 - 0.0031 = 12.4969

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
