Question

Brett took a test in which 2 points were earned for each correct response and -1/2 point was earned for each incorrect response. He answered 35 questions correctly and 15 questions incorrectly, so his total number of points was 35(2) + [-1/2(15)]. Which is another way to write Brett’s total number of points on the test?

Answer 1

2(35) - 1/2(15)
or 70 - 7.5
