Paul plans to buy a movie that has a regular price of $19.99. It is on sale for 25% off, but Paul will have to pay 6% sales tax. What is the MOST reasonable estimate of the total cost of the movie including tax?

Respuesta :

19.99 x 0.25 = $5 (rounded off)
19.99 - 5 = 14.99
14.99 x 0.06 = 0.90 (rounded off)
14.99 + 0.90 = 15.89

15.89 is the estimated total cost of the movie including tax.
