The value of Maggie's car decreased by 30% since last year, when she bought it. If the car is now worth $14,000.00, how much was the car worth when she bought it?

To find out how much the car was worth when Maggie first bought it, we simply add $4,200 to $14,000.

$14,000 + $4,200 = $18,200

a negative exponent is translated as follows:

so, we have
