A customer paid $120 for 3 sweater and 4 shirts. At the same store a customer paid $200 for 5 sweaters and 2 shirts. The price of the sweater and the shirt is the same for each customer. What is the correct system of equations. Which system equations can be used to find the price in dollars each sweater x and each shirt y?

• 5x + 2y = 120

  3x + 4y = 200

• 5y + 2x = 200

  3y + 4x = 120

• 3x + 4y = 120

  5x + 2y = 200

• 5y + 2x = 120

  3y + 4x = 200

Matt wants to spend no more than 180 minutes watching TV during the weekend. It takes 50 minutes to watch one episode of Stranger Things and 40 minutes to watch the Mandalorian. Write an inequality that represents all possible combinations of x, the number of episodes of stranger things and y number of episodes of Mandalorian.

• 50x + 40y < 180

• 50x + 40y > 180

• 40x + 50y < 180

• 40x + 50y > 180

 Larry starts at an elevation of 300 feet and ascends at a rate of 10 feet per minute. Write an equation in slope intercept form.

• y = -10x + 300

• y = 10x

• y = 10x +300

• y = 310x

Lenny goes Christmas shopping and buys $70 per switch games and $60 per extra set of controllers for $475. Write an equation where x is the switch games and y is extra controllers.

• 4x - 2y = 475

• 4y + 2x = 475

• 4x + 2y = 475

• y = 4x + 475

Sarah had $360 in her checking account. Sarah withdraws $45 a week from her account. Write an equation in slope intercept form.

• y = 45x + 360

• y = 45x -360

• y =-45x -360

• y = -45x + 360
