Question

When jose took the test over, he increased his score by 15 percentage points. jose raised his score to an 83% on the test.

which of the following equations represents the word problem if "x" represents jose’s score on the first test?
1. x-15=83
2. x+15=83
3. x=15+83

Answer 1

x + 15 = 83

Explanation:

x-15=83 shows that his first test score without the 15 points is 83, which isn't true because it says he raised it by 15 in the statement

x=15+83 shows that his first test score was 15 + 83, obviously not true because his test score was 83 - 15
