A student is asked to find the total cost of 3 notebooks priced at $2.25 each and 2 pens priced at $1.10 each, including a 6% sales tax. Which of the following steps represents the most appropriate application of mathematical reasoning to solve this problem?
- Adding the prices of all items first, then multiplying by the tax rate, and finally adding the tax to the initial total.
- Multiplying the quantity and price of each item, summing these results, multiplying the sum by the tax rate, and adding the result to the original sum. (correct)
- Calculating the tax for each item separately, adding the taxes to their respective item costs, and then summing up the total.
- Ignoring the sales tax to simplify the calculation and estimating the total cost.
