You have eaten 70% of your Halloween candy. You counted all the empty wrappers and you count 140 empty wrappers !!! How many peices of candy did you have to begin with ?

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:

To find the original amount of candy, we just have to solve for x.

So, let’s divide both sides by 0.7:

Therefore, we started out with 200 pieces of candy.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
