A college student needs 11 classes that are worth a total of 40 credits in order to complete her degree. The college offers both 4-credit classes and 3-credit classes. Which system of equations can be used to determine f, the number of 4-credit classes the student can take to complete her degree, and h, the number of 3-credit classes?

• f + h = 40
  4h + 3f = 11

• f + h = 11
  4h + 3f = 40

• f + h = 40
   4f + 3h = 11

• f + h = 11
  4f + 3h = 40
