The price of a stock decreased by 60 cents one week, decreased 10 cents the next week, and decreased another 20 cents the follow

mel-nik [20]

Hi there! Hopefully this helps!

----------------------------------------------------------------------------------------------------------

It decreased by 30 cents per week.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The average rate of change is calculated as:

the ratio of the sum of the change in the three weeks divided by the number of weeks. (The number of weeks being 3)

Rate of change = $\frac{-60 -10 -20}{3}$ .

(-60 + -10 + -20 = -90). So, to simplify it:

$\frac{-90}{3}$ = -30

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Incase you are confused:

Since the average rate of change is negative, this means that the stock price has decreased.

Three workers have to do a certain job. The first worker can finish the job in 8 hours. The second worker can finish the job in

Ainat [17]

This means that...

the first worker does 1/8 of the job each hour.

the second worker does 1/4 of the job each hour.

the third worker does 1/4 of the job each hour.

So together they get 1/8+1/4+1/4 of the job done per hour.

Rate: 5/8 of the job per hour

Now if we know the rate, the job will be finished in...

1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes

answer: 1.6 hours or 1 hour and 36 minutes
