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

x + 0.07x or 1.07x

Step-by-step explanation:

7% is 7 out of 100; 7/100 = 0.07

Finding a percent of a number means you multiply the percent by that number; this means 7% of x would be 0.07 (x) = 0.07x.

Tax is something that is added to a given price. The variable x is our given price; this means we add

x + 0.07x

This is the same as

1x + 0.07x

Combining like terms gives us

1.07x

Price is x

tax is 7%*x, or. 07x

add price and tax to get 1x+.07x or a total price of 1.07x
