Hi there! The percentage of change is 200%
We can find the percentage of change using the following formula:
[tex] \frac{new-original}{original} \times 100[/tex]
When we fill in this formula, we get the following:
[tex] \frac{150-50}{50} \times 100 = \frac{100}{50} \times 100 = 2 \times 100 = 200[/tex]
Therefore, the percentage of change is 200%
