Answer:
The percent increase is 50%
Step-by-step explanation:
The question is
Find out the percent increase
we know that
The original amount represent the 100%
so
30 represent 100%
using proportion
Determine what percentage represent the difference between the end amount and the original amount
so
[tex]\frac{30}{100\%}=\frac{45-30}{x}\\\\x=100(15)/30\\\\x=50\%[/tex]
therefore
The percent increase is 50%
