Ashopper payed $530 for an item marked $500 what is the percent of the sales tax

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

The answer would be c.8(2)=16-16=0 -8(2)=16-16=0
