Mary purchased a new drawing box. the height, width and length of the box are respectively 12 cm, 6 cm, 3 cm. she wants to fill the box with pencils. the density of a pencil is 0.03 pencils per cm cubed. how many total pencils can she fit in the drawing box?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
