The value of investments in the stock market change daily. suppose you buy a stock for $1500. it decreases in value by 5% and then rises 7%. what is the new value?

$1,524.75

Step-by-step explanation:

Percentage decrease = 5% or 0.05 as a decimal

Amount by which the stock decreased = - (1500*0.05) = -$75

So at first, the price decrease to = $1,500 - $75 = $1,425

Secondly, the percentage increase in price = 7% or 0.07 as a decimal

Amount by which the stock increased = (1,425*0.07) = $99.75

Therefore, the price rose to = $1,425 + $99.75 = $1,524.75

New value is therefore $1,524.75
