To find the percent increase from 1 to 2.9, you can use the following formula:
\[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]
In this case:
- Old Value = 1
- New Value = 2.9
Now, plug in the values:
\[ \text{Percent Increase} = \left( \frac{2.9 - 1}{1} \right) \times 100 \]
Calculate the difference:
\[ 2.9 - 1 = 1.9 \]
Now, substitute back into the formula:
\[ \text{Percent Increase} = \left( \frac{1.9}{1} \right) \times 100 = 1.9 \times 100 = 190 \]
Thus, the percent of increase from 1 to 2.9 is 190%.
