Answer:
pretty sure it is c but might wrong
Step-by-step explanation:
If 3 is the number missed, we want the percentage wrong
![\frac{10}{100} = \frac{3}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B100%7D%20%3D%20%20%20%5Cfrac%7B3%7D%7Bx%7D%20)
3(100)=10(x)
10x=300
Divide by 10
x=30
This is a 2.5% decrease in price.
