2. Neon has 2 isotopes. The relative abundance of Neon - 20 is 89.5%. The relative abundance of Neon - 22 is 10.5%. Determine the average atomic mass of
Neon.

g

step-by-step explanation:

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

i think the answer would be c
