Answer:
[tex]26.3304[/tex]
Step-by-step explanation:
Given,
The original price of the textbook = 26.50,
Also, the discount percentage = 8 %,
Thus, the price of the textbook after discount = 26.50 - 8 % of 26.50
[tex]=26.5-\frac{8\times 26.5}{100}[/tex]
[tex]=26.5-2.12[/tex]
[tex]=24.38[/tex]
Now, the sales tax = 8 %,
Hence, the cost of the textbook including sales tax = 24.38 + 8 % of 24.38
[tex]=24.38+\frac{8\times 24.38}{100}[/tex]
[tex]=24.38 + 1.9504[/tex]
[tex]=26.3304[/tex]
