Question

A stock decreased in price by $25 over 4 days. What was the mean daily decrease in price?

Answer 1

A mathematical mean is the average of a group of numbers.

The mean daily decrease would be the total amount of decrease (in this case, $25) divided by the total amount of days it took to get there (in this case, 4).

25 / 4 = 6.25 = 6
`(1)/(4)`

The mean daily decrease in price would be 6
`(1)/(4)`.
Hope that helped! =)
