Jenny wants to bankrupt her husband. To do this she must spend OVER 600 dollars. If a pair of pants costs 12 dollars, and a shirt costs 10 dollars, then write an inequality to represent the problem that will bankrupt her husband.
12x + 10y > 600

Sam and Dillon want to do a prank on Mrs. Burke. The two pranksters need AT LEAST 200 cans of fart spray to fill the room. The normal fart spray costs 10 dollars but double stinky fart spray is 20 dollars. Sam is broke, but Dillon has $400 to spend on fart spray, but no more than that. Write a system of inequalities to represent the problem. Use x and y.
x+y ≥ 200 and 10x + 20y ≤ 400
