Question

The change in Chandra's account balance over a 5-month period is −$860 .

Answer 1

Alright my friend so basically if we multiply option C. -172 x 5 the outcome will be -860

Answer 2

Answer:

-$172

Step-by-step explanation:

If the change in Chandra's account balance over a 5-month period is −$860, her average change o'er month (i.e for one month) over the period will be -$860/5

= -$860/5

= -$172

It is like taking the mean of the total balance i.e average balance for 5months/total number of months
