Here is a sales tax of $9 on an item that costs $120 before tax. the sales tax on a second item is $19.05. how much does the second item cost before tax?

% of sales tax = 9/120 x 100 = 900/120 = 7.5%

Let the cost of the second item be x, then 7.5/100 x = 19.05
0.075x = 19.05
x = 19.05/0.075 = 254.

Therefore, the cost f the second item is $254
