Final answer:

The expressions that represent how much Leila pays in total for the dinosaur model are 1.07x, 0.7x + x, and 1.7x.

Step-by-step explanation:

The correct expressions that represent how much Leila pays in total for the dinosaur model are:

  1. 1.07x
  2. 0.7x + x
  3. 1.7x

Step-by-step explanation:

Leila has to pay a 7% percent tax on the price of the model, which means she needs to add 7% of the model's price to the original price.

To calculate this, we multiply the price of the model (x) by 7/100 (or 0.07) and then add it to x:

0.7x + x = 1.7x

Alternatively, we can directly calculate the total amount including tax by multiplying the price of the model (x) by 1.07:

1.07x
