To calculate the price of the item after a 10% increase and including sales tax, you'll need to follow these steps:

4. Price of item after a 10% increase with sales tax:
a. First, calculate the 10% increase on the original price of $229.99. Multiply the original price by 10% (0.10):
229.99 * 0.10 = 22.999; round to two decimal places: 23.00.

b. Next, add the increase to the original price to get the new price after the 10% increase:
229.99 + 23.00 = 252.99.

c. Calculate the sales tax based on the new price. Sales tax rates can vary depending on your location, so you'll need to determine the applicable rate. Let's assume a sales tax rate of 8%.

d. Multiply the new price by the sales tax rate (as a decimal):
252.99 * 0.08 = 20.2392.

e. Add the sales tax to the new price to get the final price after the 10% increase with sales tax:
252.99 + 20.2392 = 273.23 (rounded to two decimal places).

5. Final Price:
The final price, after the 10% increase with sales tax, will be $273.23.
