Calculate a three-day weighted moving average for the price of the stock for the end of Day 7 where the most recent price has a
postnew [5]

The three-day weighted moving average for the price of the stock at the end of Day 7 is 57.17.

<h3>How do we calculate a weighted moving average?</h3>

Note that since this is for the end of Day 7, it implies that the actual Day 7 Stock Price is not yet known at the time of the calculation and we need to forecast it.

Therefore, the most recent price is Day 6 Sock Price and a three-day weighted moving average for this question can be calculated as follows:

Three-day weighted moving average = ((Day 6 Sock Price * 3) + (Day 5 Sock Price * 2) + (Day 4 Sock Price * 1)) / (3 + 2 + 1)

Three-day weighted moving average = ((55.00 * 3) + (59.00 * 2) + (60.00 * 1)) / (3 + 2 + 1)

Three-day weighted moving average = 57.17

Caroline's coffee shop sells a refill mug for $8.95. Each refill cost $1.50. Last month Sean spent $26.95 on a mug and refills.
Talja [164]
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
 (26.95 - 8.95) ÷ 1.50 = r 

Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.

Hope this helps :).
