Step-by-step explanation:
To find the total amount, including sales tax for an item with a price tag of $9.78 and a sales tax rate of 9.5%, we need to calculate the amount of sales tax and then add it to the original price.

Finally, we add the sales tax to the original price to find the total amount: $9.78 + $0.93 = $10.71.
Therefore, option 1: $10.70 is the closest value to the total amount including sales tax for an item with a price tag of $9.78 and a sales tax rate of 9.5%.
