Right.
OK Cool, but so I can understand well can you explain me how? Please? !
7.80 = original price
1.1 - amount of price increase
1.075 = price plus sales tax
OK, I got it now! Thanks so much!

To find the final price of the item after a 10% increase and sales tax, we can follow these steps:
Step 1: Calculate the price increase:
To increase the price by 10%, multiply the original price by 0.10:
Price_increase = $7.80 * 0.10 = $0.78
Step 2: Add the price increase to the original price to get the new price:
New_Price = $7.80 + $0.78 = $8.58
Step 3: Calculate the sales tax amount:
To find the sales tax amount, multiply the new price by the sales tax rate:
Sales_Tax_Amount = $8.58 * 0.075 = $0.6445
Step 4: Add the sales tax amount to the new price:
Final_Price = $8.58 + $0.6445 = $9.2245 (rounded to two decimal places)
Therefore, the price of the item after a 10% increase with sales tax is $9.22.
