a cell phone was on sale for 30% off. the discounted price was $210.00. what was the original price of the phone?

To find the original price of the phone before the discount, we can use the following relationship:

The discounted price is 70% of the original price (because 30% off means you pay 70% of the full price). Let $ P $ be the original price.

We know:

\[
0.70 \times P = 210
\]

To find $ P $, divide both sides by 0.70:

\[
P = \frac{210}{0.70} = 300
\]

So, the original price of the phone was **$300**.
