Answer:

10% decrease

Step-by-step explanation:

The formula for percent change is:

$\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100$

Therefore, for this example:

$\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100=\frac{135-150}{150} \times 100=-10\%$

The negative value indicates that the change was a decrease. Therefore, there was a 10% decrease.
