Answer:
10% decrease
Step-by-step explanation:
The formula for percent change is:
[tex]\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100[/tex]
Therefore, for this example:
[tex]\frac{\textrm{New}-\textrm{Old}}{\textrm{Old}} \times 100=\frac{135-150}{150} \times 100=-10\%[/tex]
The negative value indicates that the change was a decrease. Therefore, there was a 10% decrease.
