The cost of a cell phone was $200. Then it was discounted by 10%. What is the new cost of the cell phone? Explain what you did to solve the problem

The answer is $180. So I did 10%x200=20 take that and then do 200-20=180

Answer with explanation:

You first have to find 10% of $200. To do this, you have to multiply the decimal form of 10% with 200.

So,

10% of 200

0.1 of 200

0.1 * 200 = 20

Now since the 10% acts as a discount, you subtract the 10% of 200 from $200.

$200 - 20 = $180

So the new price of the phone is $180.
