Answer:
it's $75
Explanation:
Since to find the change in the value of Jairo's shares, we would first need to calculate the new value of each share.
On Monday, each share was worth 2 dollars more than the previous day, so each share was now worth 2+5 = $7.
On Tuesday, the value dropped 5 dollars per share, so each share was now worth 7-5 = $2.
This means the value of Jairo's shares decreased by 5 dollars.
5 x 15 = 75
So as a whole, Jairo's shares have dipped by $75.
