Question

Daniel invested in stock market. The price of one share of stock fell 12 dollars each day for 8 days. How much money did Daniel lose after 8 days

-48 dollars
96 dollars
100 dollars
-96 dollars

The correct answer is: -96 dollars

Given:-Price of one share of stack Fell each day =$12 since, price is getting lower
Price of each share fell each day can be counted as -12 dollars
The same goes on for 8 days
Money daniel loses after 8 days can be calculated as
$rightwards double arrow negative 12 cross times 8$ dollars
$rightwards double arrow negative 96$ dollars
[Negative no multiplied with positive number, results in negative.]
