Answer:
B. 85%
Step-by-step explanation:
in order to find out her percentage, you want to do 17/20
the reason we do 17/20 and not 20/17 is because 20/17 gives you 1.1, which is both not an option and does not make logical sense
17/20 = 0.85
in order to make this a percentage, multiply 0.85 by 100
0.85 x 100 = 85
so your answer is 85%, or B
