Lola bought x pencils that cost $0.25 each and y erasers that cost $0.50. she spent less than $3. which graph represents lola’s purchase?

Answer with explanation:

Cost of a Pencil = $ 0.25

Cost of a Eraser = $ 0.50

⇒Total Amount Spent on Pencil and Eraser < 3.

⇒Cost of x Pencil +Cost of y Eraser < 3

⇒ 0.25 x + 0.50 y < 3

⇒Put, x=0 and y=0,to know which side of the graph you have to shade.

0+0< 12⇒0< 12

Shade that part under line,  which contains origin.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
