Final answer:
The total cost for 10 corrugated shipping boxes, each priced at $2.31, with an additional tax of $1.89, is $25.99.
Step-by-step explanation:
The cost of one corrugated box for shipping is $2.31. To find the total cost for 10 boxes, we simply multiply the cost of one box by the quantity which is 10. So, the calculation is $2.31 × 10 = $23.10. However, we also need to include a fixed tax amount of $1.89. Therefore, we add the tax to the total cost of the boxes to find the final amount payable.
Final cost including tax = Cost of boxes + Tax = $23.10 + $1.89 = $25.99.
This calculation provides the total cost for 10 corrugated boxes including the tax.
