John just purchased a new car with a value of $35,000. The car loses value at a rate of 7.5%. Which equation best represents this situation if y is the value of the car and x is the number of years he has owned the car?

a. y=35000(0.925)^x b. y=1.75(35000)^x c. y=35000(1.075)^x d. y=0.25(35000)^x e. y=35000(1.75)^x f. y=35000(0.25)^x g. y=1.075(35000)^x h. y=0.925(35000)^x
