In one year, the Dow Jones Industrial Average increased from 3,945 to 4,386. What percent increase does this represent to the nearest tenth of a percent?
And your answer is??
How did you get that? I got a much different answer.
I divide 3945/4386=0.89, then I just rounded to 1%.
Ah -- you forgot the subtraction part.
4,386 - 3,945 = 441
Now compare that difference with the original number.
441/3,945 = ?
We can prove an answer by reversing the procedure.
3,945 * 0.1 = 394.5
3,945 + 394.5 does not equal 4,386.
To find the percent increase, you need to calculate the difference between the initial value and the final value, and then divide it by the initial value. Finally, multiply the result by 100 to get the percentage. Here's how you can calculate it step by step:
1. Find the difference between the final value and the initial value:
Difference = Final Value - Initial Value
Difference = 4386 - 3945
Difference = 441
2. Divide the difference by the initial value:
Percent Increase = (Difference / Initial Value) * 100
Percent Increase = (441 / 3945) * 100
Percent Increase = 0.1117 * 100
Percent Increase ≈ 11.17
To the nearest tenth of a percent, the Dow Jones Industrial Average increased by approximately 11.2%.
