Solution:
Given that,
Amanda answered all the questions on her math test but got 10 answers wrong
She received 4 points for every correct answer, and there were no points for wrong answers
Find the number of questions answered correctly:
Her final score was 76 points
4 points for every correct answer
Thus,
[tex]correct\ answers = \frac{76}{4} = 19[/tex]
From given.
Incorrect answers = 10
Let "x" be the total number of questions on his math test
Then,
x = correct answered questions + incorrect answered questions
x = 19 + 10
x = 29
Thus there are 29 total number of questions on his math test
