Answer:
200 pieces of candy.
Step-by-step explanation:
Let x represent the amount of candy we had to begin with.
We ate 70% or 0.7 of our starting amount x.
After eating 70% of x, we are left with 140 empty wrappers.
Therefore, 70% or 0.7 of x is 140. So, we can write the following equation:
![0.7x=140](https://tex.z-dn.net/?f=0.7x%3D140)
To find the original amount of candy, we just have to solve for x.
So, let’s divide both sides by 0.7:
![\displaystyle x=\frac{140}{.7}=200](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%3D%5Cfrac%7B140%7D%7B.7%7D%3D200)
Therefore, we started out with 200 pieces of candy.
