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.0It's a question in proportions. 1800 is to 25000 as 1600 is to x. Are you with me so far?

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
