The answer is 10!!!
Above is wrongTo work it backwards.(A - 13) X 8 = 80
80 Divided by 8 = 10
10 + 13 = 23
A = 23
To check put the answer into the original equation

If you make an average of 78 on your last seven exams how high would you have to score to obtain an 80 average?
you would need a 94. Multiply your current average of 78 times 7 to get to 546. To have an average of 80, you multiply 80 *8 to get 640. 8 represents the total number of exams you have taken. I am assuming the question is "what does the student need to score on his eighth exam to get an 80 for the semester?" subtract 546 from 640 and you get 94.
