Answer:

$\frac{7}{100} * x$

Step-by-step explanation:

7%, do you know where percent come from? Per Cent. The per means one while cent is used in centimeter & etc... Which means 100. So percent means 1 over 100. So 7% means 7 over 100 or $\frac{7}{100}$. So if the dinosaur model is 5 dollars, plus 7% tax. First, you will have to find what is 7% of 5 dollars. So you will have to do... $\frac{7}{100} * 5$ . The word "of" means multiply. Then you will get 0.35 cents. So 0.35 cents (which is the amounts of the tax) plus 5 for example (or x), you would get 5.35%, which is the amount you have to give. So basically, the formula is $\frac{7}{100} * x$.
