There are 29 total number of questions on his math test

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,


correct\ answers = (76)/(4) = 19

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
