Pam scored 78 on a test that had 4 fill-in questions worth 7 points each and 24 multiple choice questions worth 3 points each. She had one fill-in question wrong.How many multiple choice questions did Pam get right?
One fill-in question wrong, so she got
100-7=93 before multiple choice (78).
So she lost 93-78=15 on multiple choice.
How many multiple-choice did she get wrong?
