Step-by-step explanation:

Answer 2

Answer:

All satisfy the conditions

Step-by-step explanation:

Interpreting (x,y) as (movies, video games) then each of these points work.

He must buy 9 items at least and spend $400. Each of these options are more than 9 items and their prices add to $400.

(5,6) = 5(20) + 6(50) = 100+300=400

(10,4) = 10(20) + 4(50) = 200+200=400

(20,0) = 20(20) + 0(50) = 400+0=400

(15,2) = 15(20) + 2(50) = 300 + 100 = 400
