College students are offered a 8% discount on a textbook that sells for 26.50. If the sales tax is 8, find the cost of the textbook including sales tax.

Sagot :

IF THE BOOK COSTS 26.50 AND YOU GET A DISCOUNT OF 8%, YOU NEED TO FIND OUT HOW MUCH IS 8% OF 26.50, WHICH IS IS 2.12 DISCOUNT
SO YOUR BOOK COSTS NOW 26.50-2.12=24.38
NOW, IF YOU WILL PAY 8% TAXES, EIGHT PERCENT OF 24.38 IS 1.95
YOUR BOOK WILL COST 24.38+1.95=26.33

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]
