Steps to Solve
- Identify the old and new values
In this problem, the old value is 90 and the new value is 130.
- Calculate the difference between the new and old values
We subtract the old value from the new value to find the change:
$$ 130 - 90 = 40 $$
- Divide the difference by the old value
Next, we calculate the ratio of the difference to the old value:
$$ \frac{40}{90} $$
- Convert the ratio to a percentage
To find the percentage increase, multiply the result from the previous step by 100:
$$ \left(\frac{40}{90}\right) \times 100 \approx 44.44 $$
- State the final answer
The percentage increase from 90 to 130 is approximately 44.44%.
