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?

x = 15 + 83
x + 15 = 83
x - 15 = 83

Answer 1

So, given that Jose's second score was an 83%, you would separate the 83 from the rest of the equation.

\(83=?\)

Now it says that 15 percentage points were added to the previous score, which would give you.

\(x+15\)

So you would end up with the equation.

\(x+15=83\)

OVERVIEW:
- Find the lone variable, which was the second test score.
- Previous score was increased (addition, +) by 15
- Answer found by adding the lone variable and \(x+15\) to an equation.
