Alana bought a stock, which dropped 10% from the previous day. The value of her stock, after the price drop was $305 Wh ch equat

White raven [17]

If the original price was 'p', the new price would be 'p - 10%p' or 'p - 0.1p'. We know this is equal to 305, so 'p - 0.1 p = 305' would be the equation.
