Tabitha wants to find the total cost of a new tablet computer that has an original cost of $360 from a store having a 20% off sale on all tablets. She also wants to make sure
she includes the costs of the 6.5% sales tax. Tabitha uses the incorrect expression (360) (0.8) (.935) to calculate that the tablet will cost a total of $269.28.
ch statement explains the error in her expression?
She found the discount by multiplying the original price by 0.8 instead of by 0.2, and she applied the tax rate as a discount instead of as an increase; she should
have used (360) (0.2) (1.065).
