In four days,the total change in value -$12.60.
According to the statement
we have given that the value of an investment changed at a rate of -$3.15 each day. And we have to find that the after how many days the change in value reaches at the -$12.60.
So, here we use division rule to find the solution.
The given change value is :
-$3.15 each day.
The desired change value is :
-$12.60.
Number of days required = -12.60 / -3.15
Number of days required = 12.60 / 3.15
Number of days required = 4 days.
So, in four days the change in value reaches at the desired value of change.
So, In four days,the total change in value -$12.60.
