If you increase your current quality score of 85% by 7%, you will have a score of _
The Correct Answer and Explanation is:
Correct Answer: 90.95%
Explanation
To calculate a 7% increase on a current score of 85%, we are looking to find 7% of 85 and then add that to 85.
Step 1: Convert the Percentage Increase to a Decimal
Percent means “per hundred,” so:
7% = 7 ÷ 100 = 0.07
Step 2: Multiply the Current Score by the Decimal
Now, we find 7% of 85:
0.07 × 85 = 5.95
This result (5.95) is the amount by which the score increases.
Step 3: Add the Increase to the Original Score
85 + 5.95 = 90.95
So, increasing 85% by 7% gives a new score of 90.95%.
Why It’s Not Just 85 + 7 = 92
A common mistake is to simply add 7 to 85 and get 92%. But a 7% increase is not the same as adding 7 percentage points. Rather, it means adding 7 percent of the original number.
If your score was 85%, then 7% of that is 5.95. You’re not adding 7 directly—you’re adding a portion of 85.
This distinction is important in many real-world contexts—such as interest rates, salary increases, and performance metrics—where percent increase or decrease refers to a proportion of the original value, not just a fixed number.
Summary
Increasing 85% by 7% means:
- Find 7% of 85 → 5.95
- Add to 85 → 90.95%
Hence, your new score is 90.95%.
