mark got 14 problems wrong on his test. his score was 72%. how many problems were on the test

Answer 1

If 72% were correct, then 28% were wrong. Those were the 14 questions shown in the intro.

14 is 28% of what number? 14 = 0.28x, so x = 14/0.28 = 50 total questions on the test.

Check: 72% of 50 = 36 correct; 50 - 36 = 14 wrong.

Note: Assumes each question carries the same weight.

Answer 2

If he got 72% correct, then 28% were not correct.

Let x be the total number of questions on the test.

28% of x = 14

0.28x = 14

x = 50

Answer 3

If he got 72% correct then he got 28% wrong
