Question

A store is having a 20% off sale. The sale price of an item with price p is p – 0.2p. What is an equivalent expression?

Answer 1

Answer:

0.8p

Step-by-step explanation:

We are given that there is a 20% sale in the store.

Moreover, the sale price of an item is p - 0.2p, where p is the price of the item.

Now, p - 0.2p = ( 1-0.2 )p = 0.8p

So, we get that,

p - 0.2p is equivalent to 0.8p.

Hence, the equivalent expression to the sale price of an item is 0.8p, where p is the price of the item.

Answer 2

If it is 20% off, then ur actually paying 80%
so an equivalent expression would be 0.80p
