Melissa earned a score of 75% on her first
test. She wants to earn an 85% on her second test. What is the percent increase,
rounded to the nearest whole number,
from 75% to 85%?
Do 85 dived by 75 to get your answer in percentage
10%
To find the percent increase from 75% to 85%, we can use the following formula:
Percent increase = ((New value - Old value) / Old value) * 100
Let's calculate the percent increase step-by-step:
1. Convert the percentages to decimals:
Old value = 75% = 0.75
New value = 85% = 0.85
2. Calculate the difference between the new and old values:
Difference = New value - Old value
= 0.85 - 0.75
= 0.10
3. Calculate the percent increase:
Percent increase = (Difference / Old value) * 100
= (0.10 / 0.75) * 100
= 0.133333... * 100
≈ 13.33
Rounded to the nearest whole number, the percent increase from 75% to 85% is approximately 13%.
To find the percent increase from 75% to 85%, you need to follow these steps:
Step 1: Calculate the difference between the two percentages.
The difference can be found by subtracting the starting percentage (75%) from the ending percentage (85%).
Difference = 85% - 75%
Step 2: Divide the difference by the starting percentage.
Divide the difference calculated in step 1 by the starting percentage (75%).
Percent Increase = (Difference / Starting Percentage) * 100
Step 3: Round the calculated percent increase to the nearest whole number.
Round the obtained value from step 2 to the nearest whole number.
Let's solve it.
Step 1:
Difference = 85% - 75%
= 10%
Step 2:
Percent Increase = (10% / 75%) * 100
To calculate 10% of 75%, multiply 10/100 by 75.
Percent Increase = (10/100) * 75
= 0.10 * 75
= 7.5
Step 3:
Round the value 7.5 to the nearest whole number, which is 8.
Therefore, the percent increase from 75% to 85% is approximately 8%.
