Make a proportion the sales tax is a percent of the total purchase and you just have to figure that out. 1,200/100=72/x solving this i get 6% sales tax using that. I find the rest by taking 6% of 2500 =150. And for part b make another proprtion x/100=108/6. And i get 1800 dollars
72 I believe because you have to subtract the 33 from the number of total games & then divide by two because you already took out the 33 more loses than wins.
