These tables of ordered pairs represent some points on the graphs of lines p and r. Which system of equations is represented by lines p and r? 9x−4y=−92x+4y=15 x−2y=−86x+5y=30 3x−y=−127x+3y=21 2x−y=−82x+y=7

it is probably the graph on the bottom right.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.
