Final answer:
The total cost of Kayombought's new outfit, including sales tax, is $299.93.
Step-by-step explanation:
To find the total cost of Kayombought's new outfit, we need to add up the costs of the dress, shoes, nylons, and necklace. The sales tax is 5.5%, so we also need to calculate the tax and add it to the total. Let's break it down:
- The dress costs $143.50
- The shoes cost $65.90
- The nylons cost $4.99
- The necklace costs $69.90
Now, let's find the total amount spent on the outfit without tax:
- Total without tax = $143.50 + $65.90 + $4.99 + $69.90 = $284.29
Next, we'll find the sales tax amount:
- Sales tax = 5.5% * $284.29 = $15.64
Finally, we'll add the sales tax to the total without tax:
- Total cost of the outfit = $284.29 + $15.64 = $299.93
Therefore, Kayombought's new outfit cost $299.93, option a) $295.16 is the closest answer choice.
