Firstly, you should find the discount that is taken off of the jacket, and then also find the sales tax. As the discount is 10%, you simply have to divide 35 by 10. 35/10= 3.50. Therefore, you need to subtract the 3.50 from the 35, which gives you 31.50. You've then got the 5% sales tax to add on, which is 3.50/2= 1.75, you've then got to add 1.75 to 31.50, which gives you 33.25. However, if the sales tax is on the discounted price, then it will be 31.50/10= 3.15/2= 1.58, and you've then got to add this is to discount price, which is 31.50+1.58= 33.08
