A math teacher gave her class a test that consisted of 30 problems. Some of the problems were worth 4 points each and the rest of the problems were worth 2 points each. If there were a total of 100 points on the test, then how many problems on the test were worth 4 points each and how many problems on the test were worth 2 points each? 16. Let x represent the number of problems on the test that were worth 4 points and let y represent the number of problems on the test that were worth 2 points. Write a system of linear equations. A) x+y=100 2x+4y= 30 A) 18 B) 10 A) 18 B) 17. How many problems on the test were worth 4 points each? x+y=30 4x+2y=100 B) 10 C) 15 C) x+y=30 2x+4y=100 18. How many problems on the test were worth 2 points each? C) 15 D) 12 D) 12 E) 20 E) 20 D) x+y=100 4x+2y=30
