Help please!? The sales tax on a new car varies directly to(or is directly proportional) the price of the car. If $1,800 in sales tax is paid for a $25,000 car. what is the purchase price of a car worth $1,600 in sales tax? Im totally lost when it comes to variations :(

Best ResponseYou've already chosen the best response.0"varies directly" is the same as proportions. You will use an equation like a/b = c/x.

Best ResponseYou've already chosen the best response.025000/1800 = x/1600 25000/1800 = 13.89 1800 x 13.89 = 25 1600 x 13.89 = x
