The answer is B
100% - 13% = 87% or .87
Tax is 8% or .08
Total cost would be 1 + .08 x .87
or 1.08(0.87y)

Solution: The correct option is option (B) 1.08(0.87y).

Step-by-step explanation:

It is given that the original cost of cards is y. It is also given that cards was on sale of 13% and the tax in the country is 8%.

There is a sale of 13% it means the prices are 13% less.

13% of y =
(13)/(100) (y)

The price of cards after discount is


y-(13)/(100) (y)=(87)/(100) (y)=0.87y

The price after discount is 0.87y.

It is given that the tax in the country is 8%.

The amount of tax on the cards is calculated as shown below,


(8)/(100)(0.87y)=0.08(0.87y)

The price after discount is is calculated as shown below,


0.87y+0.08(0.87y)=1.08(0.87y)

Therefore, the correct option is option (B) 1.08(0.87y).
