Question

What is the percent change from 40 to 51?

Answer 1

27.5%

Explanation:

To calculate the percent change from 40 to 51, we can use the following formula:

Percent Change = (New Value - Old Value) / Old Value x 100%

In this case, the old value is 40, and the new value is 51.

So, plugging these values into the formula, we get:

Percent Change = (51 - 40) / 40 x 100%

Percent Change = 11 / 40 x 100%

Percent Change = 0.275 x 100%

Percent Change = 27.5%

Therefore, the percent change from 40 to 51 is 27.5%.

Answer 2

27.5%

Explanation:

Given: the percent increase from 40 to 51

Percent change = 51 - 40 |40| × 100% = 11 40 × 100 = 27.5% (increase).

Where: 40 is the old value and 51 is the new value. In this case we have a positive change (increase) of 27.5 percent because the new value is greater than the old value.
