On a test, if 110 questions are answered and 38% of them are correct, what is the number of correct answers?

If 100% of the answers are correct ; 1*110 = 110 answers are correct.
if 50% of the answers are correct ; 0.5*110 = 55 answers are correct.
if 38% of the answers are correct ; 0.38*110 = 41.8 answers are correct.

Because the number of answers needs to be a whole number; the number of correct answers is 41.

Step-by-step explanation:

120 = 2x + 70

120  - 70 = 2x + 70 - 70

50 = 2x

50/2 = 2x/2

x = 25
