Answer 1

Answer:

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.

Which of the following expressions could represent how much Leila pays in total for the model?

Step-by-step explanation:

The original price of the dinosaur model is "x" dollars

On top of that, the sales tax is 7% of the original price

Hence,

The total price would be the original amount PLUS the taxed amount

Original Amount = x

Taxed Amount = 7% of x

That is, 7% in decimal multiplied with "x".

7/100 = 0.07

0.07 * x = 0.07x

Total amount = x + 0.07x = 1.07x

The expression for total amount is 1.07x

Answer 2

Answer:

1.07x

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Leila is buying a dinosaur model. The price of the model is x dollars, and she also has to pay a 7%, percent tax.

Which of the following expressions could represent how much Leila pays in total for the model?

My answer:

Given the information:

The original price of the model: x

Taxed Amount = 7% of x

<=> That is, 7% in decimal multiplied with "x"

<=> $\frac{7}{100}x$ = 0.07x

=> Total amount Leila needs to pay is:

= The original price + Taxed Amount

= x + 0.07x

= 1.07x

Therefore, the expressions could represent how much Leila pays in total for the model 1.07x

Hope it will find you well.
