A store has a 20% sale on everything. An item originally cost 350 AED. What is the sale price? Show your work of how you calcula

Answer:

Step-by-step explanation:

A store has a 20% sale on everything.

So since you are saving 20%, you will only be paying 80% of the original price.

To find the sale price use the following formula:

Sale price = 80% x original price

They told us the original price = 350 AED

This means:

Sale price = 80% x 350

I think it would be easiest to change 80% into a fraction if you don't have a calculator :)

80% = $\frac{80}{100} = \frac{4}{5}$

This means that the

Sale Price= $\frac{4}{5}$ x 350 = 280 AED

What is the median of this data set? {10, 15, 12, 6, 2}

Hello there!

Median is the middle of the data set.

So, first we have to arrange it into proper numerical order (least to greatest).

2,6,10,12,15

Then, we look for the middle number.

It is 10, therefore 10 would be the median of this data set.
