Lucy can buy up to 12 pencils at the store. The cost of the pencils is shown in
the graph. What is the domain?

th domain is 6$ dollar and c . all whole numbers from 0 to 12

x = 3 ± √(5+y)

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
