Answer 2

Answer: Option 'B' is correct.

Explanation:

Since we have given that

Regular price of a smart phone be x

According to question, the new price is 25% more than the older model.

So, New price becomes

`(100+25)/(100)* x\\\\=(125)/(100)* x\\\\=1.25* x\\\\=1.25x`

The upgraded phone's price can be represented by 1.25x.

Hence, Option 'B' is correct.
