Question

Find each percent decrease. Rounf to thr nearest percent. The first one is done for you.From $60 to $40?

Answer 1

So the 100% percent is equal to $60 and is decreasing $40 so is:

`60-40=20`

So is decreasing $20. now we can made a rule of 3 to finde the percentage so:

`\begin{gathered} 60\to100 \\ 20\to x \end{gathered}`

and the ecuation will be:

`\begin{gathered} x=(100\cdot20)/(60) \\ x=33.33\approx33 \end{gathered}`

So in total the decrese a 33%
