Question

The value of Maggie's car decreased by 30% since last year, when she bought it. If the car is now worth $17,000.00, how much was the car worth when she bought it?

Answer 1

The right answer would be if it would decreased by 30% you would have to multiply 17,000 by 30% then subtract what you get from 17,000

17,000 x .30 = 5100
17,000 - 5100 = 11,900

Answer 2

v- .3v=18000

.7v=18000

v=18000

.7
