If Adam Orders a Book from Store X, How Much Will He Owe to the Nearest Cent?
Understanding the Problem
In this problem, we are given a scenario where Adam orders a book from Store X, and we need to determine the amount he will owe to the nearest cent. The tax rate only applies to the cost of the book, and we need to calculate the total amount Adam will owe, including the tax.
Given Information
- The cost of the book is $15.00.
- The tax rate is 8% of the cost of the book.
Calculating the Tax
To calculate the tax, we need to multiply the cost of the book by the tax rate.
Tax = Cost of the book x Tax rate Tax = $15.00 x 0.08 Tax = $1.20
Calculating the Total Amount
To calculate the total amount Adam will owe, we need to add the cost of the book and the tax.
Total Amount = Cost of the book + Tax Total Amount = $15.00 + $1.20 Total Amount = $16.20
Rounding to the Nearest Cent
Since we need to round the total amount to the nearest cent, we can round $16.20 to $16.20.
Conclusion
In conclusion, if Adam orders a book from Store X, he will owe $16.20 to the nearest cent.
Comparison of Online Bookstores
| Store | Cost of the Book | Tax Rate | Total Amount |
|---|---|---|---|
| Store X | $15.00 | 8% | $16.20 |
| Store Y | $15.00 | 10% | $16.50 |
| Store Z | $15.00 | 12% | $16.80 |
Discussion
In this comparison, we can see that Store X has the lowest total amount, followed by Store Y and Store Z. This means that Adam will owe the least amount if he orders the book from Store X.
Mathematical Representation
Let's represent the problem mathematically. Let C be the cost of the book, T be the tax rate, and A be the total amount.
A = C + (C x T) A = C + CT A = C(1 + T)
In this case, C = $15.00, T = 0.08, and A = $16.20.
Solution
Substituting the values, we get:
A = $15.00(1 + 0.08) A = $15.00 x 1.08 A = $16.20
Final Answer
The final answer is $16.20.
