Lily spent $30 on a t-shirt a sandwich and two books the t-shirt cost $8.95 in the sandwich cost $7.25 the books each cost the same amount how much do each book cost

The cost of each book is $6.90.

Step-by-step explanation:

Given:

Lily spent $30 on a T-shirt a sandwich and two books the T-shirt cost $8.95 in the sandwich cost $7.25 the books each cost the same amount.

Now, to find the cost of each book.

Total amount Lily spent = $30.

Cost of T-shirt = $8.95.

Cost of sandwich = $7.25.

So, we get the amount after deducting the cost of T-shirt and sandwich from total amount spent:

The remaining amount = $13.80.

As, given the books each cost the same amount. And there are 2 books.

Now, to get the cost of each books by dividing the remaining amount by 2:

Therefore, the cost of each book is $6.90.

Well, since we're finding the total amount of shows, I would do 100% - 21% which is 79%. So we're finding 79% of the total shows.

So I will find 79% of 13 which is 10.27. Then I will add 10.27 + 18 to get 28.27.

Correct me if I am wrong.
