61%
Work Step by Step
First, we need to know the formula for the percent of increase $\frac{new - origional}{origional} \times 100= $ % of increase
Now, we just need to plug the numbers into the equation.
$\frac{4500 - 2800}{2800} \times 100 $
So, the solution will be:
60.71428571428571%
Round it to the nearest %
