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.

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
