Answer
There was a 50% increase
Work Step by Step
This can be solved using the percent change formula:
percent change =$\frac{1500-1000}{1000}$
simplify
percent change =$\frac{500}{1000}$
divide
$\frac{1500-1000}{1000}=0.50$
move the decimal two places to the left to convert to percent
$0.50=50$%
There was a 50% increase
