A store manager purchased 12 more coffee mugs than key chains. Each coffee mug costs $5.25, and each key chain costs $3.50. If the manager spent a total of $194.25, which system of equations can be used to find x, the number of coffee mugs purchased, and y, the number of key chains purchased?

• x+y=12
  3.50x+5.25y=194.25

• x-y=12
  3.50+5.25y=194.25

• x+y=12
  5.25x+3.50y=194.25

• x-y=12
  5.25x+3.50y=194.25
