There is a sales tax of $6 on an item that casts $88 before tax. the sales tax on a second item is $21 how much does the second item cost before tax

Tax= (6/88)

= (3/44) %

Second item = 21(44/3)

= $308

you can see it this way

3/44 is the ideal fraction to calculate tax. The second item requires you to make 21 the tax instead of 3, which you can easily do by multiplying 3 by 7. When you do the same to the 44, you get the price of the second item before tax, which is $308.
