1. determine the sales forecast for this week using a 2-week moving average.

Sales forecast for this week is 1,280 units

Explanation: From the above question, sales for the past six weeks has been given and from the analysis of the information given.

From the information on sales six weeks ago, we found out that the sales on was 160 units, five weeks ago was 320 units, for weeks ago was 480 units, 3 weeks ago was 640, 2 weeks ago was 800 units, 1 week ago was 960 units. from the details above, weekly sales has a moving weekly average of 160 units.

calculating the sales fro this week using a 2 week moving average is

sales for one week ago as 960 units + 160*2

= 960+320

=1,280 units
