Final answer:
To calculate the total cost of a floral arrangement with a retail cost and a tax rate, multiply the retail cost by the tax rate to find the tax amount. Then, add the retail cost and the tax amount to get the total cost.
Step-by-step explanation:
To calculate the total cost of a floral arrangement, we need to add the retail cost and the tax. The tax rate is 6.33%, so we can find the tax amount by multiplying the retail cost by 6.33% (0.0633).
Tax amount = $199.99 * 0.0633 = $12.69.
Finally, we can calculate the total cost by adding the retail cost and the tax amount.
Total cost = $199.99 + $12.69 = $212.68.
