she lost 2 points for each of the 5 questions she got wrong she got all 3 extra credit questions correct and received 5 points for each what is the total number of points she gained or lost overall?
Ok so she lost 10 points in total, as she got 15 points for the questions she got correct because she got 3 credit questions correct as she got 5 questions wrong, and 3 times 5 equal 15 as 2 times 5 equal 10.
