You buy a container of cat litter for $12.25 and a bag of cat food for x dollars. the total purchase is $19.08, which includes 6% sales tax. write and solve an equation to find the cost of the cat food

The answer is 6.83 because the equation would be 12.25+x=19.06 and the opposite of addition is subtraction so you subtract the numbers given which is 12.25 and 19.06 which will give you 6.83(btw idk the 2nd part of the question where it talk about 6% sales taxes but if I find an answer I will put it down)
