Leila is buying a dinosaur model. The price of the model is x dollars, and she also has to pay a 7% tax which of the following expressions could represent how much leila pays in total for the model

Leila pays 1.07x dollars in total for the model.

Step-by-step explanation:

We are given that,

Price of the model in dollars = x

Tax applied on the price = 7%

That is, price of the tax = 7% of the original price = 7% of x = 0.07x

Thus, the new price after applying the tax is given by,

New price = Original Price + Tax price

i. e. New price = x + 0.07x

i. e. New price = 1.07x

Thus, Leila pays 1.07x dollars in total for the model.
