Answer:

29 questions on his test

Explanation:

set it up as fractions equal to each other so that you can solve for x


76\%= (76)/(100)

x is the total number of questions on the test

we know that samuel got 22 of those questions correct, and a grade is calculated by dividing the number of correct answers by the total number of questions, so we can write


(76)/(100)=(22)/(x)

then you can solve by cross multiplying


76x = 22 (100)


76x=2200

get the x by itself by dividing both sides by 76, and then you have x


(76x)/(76)=(2200)/(76)


x=(2200)/(76)=28.947

since you're not going to have .947 of a question, round it up to 29

and then you have it


x=29
