Answer:
72%
Step-by-step explanation:
Start by turning both percentages into decimals. To do this take the percent and divide it by 100. So, 60% = 60/100 or .6 and 80% = 80/100 or .8.
Next the student has already completed 20 quizzes. So, 50-20=30 remaining quizzes.
Quizzes already taken:

= 12 passed quizzes.
The remaining quizzes for the school year:

= 24 quizzes
So, Finally add them both together and divide by the total amount of quizzes:
12+24
= 36 passed quizzes

=.72
Now to convert it back into a fraction you multiply the decimal by 100.

= 72%
