Question

A stock market fell 75 points over a period of 5 days. What was the average change in the stock market each day?​

Answer 1

15 points

Explanation:

Divide the 75 points by the five days to find the average points lost per day.

75 points / 5 days = 15 points per day

Answer 2

Explanation:

In 5 days there was a 75 point loss

In 1 day there was a loss of x (which would be the average per day)

5/75 = 1/x Cross multiply

5x = 75 * 1

5x = 75 Divide by 5

5x/5 = 75/5 Do the division

x = 15

The average loss was 15 points a day.
