1.25x

because 25% can be represented as 0.25. so as the new price would be 125% of the old one its 1.25x

Answer: Option 'B' is correct.

Step-by-step 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

[tex]\frac{100+25}{100}\times x\\\\=\frac{125}{100}\times x\\\\=1.25\times x\\\\=1.25x[/tex]

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

Hence, Option 'B' is correct.
