Torri had $20 to buy a birthday present for her dad. She decided to buy a DVD for $18. The sales tax is 7%. Does que have enough money? Explain your reasoning.

Answer: Yes

Sales Tax = 7% of the 18$, which means we should multiply 18 by 0.07:

18 * 0.07 = 1.26

Sales tax = 1.26$

Now we have to add the sales tax to the original cost of the DVD which is 18$:

18 + 1.26 = 19.26

So the total cost is 19.26$

Since she has 20$, she then has enough money.
