Given:
A stock loses $1.50 each day over a five-day period.
To find:
The total change in the value of the stock at the end of five days.
Solution:
Stock loses each day = $1.50
We know that, loss or reduction represented as negative change.
So, change in the value of the stock per day = -$1.50
Change in the value of the stock in 5 days = 5×(-$1.50)
= -$7.50
Therefore, the change in the value of the stock at the end of five days is -$7.50. It means, the value of the stock loses $7.50 at the end of five days.
