Answer:

The correct option is E,14

Step-by-step explanation:

In using the two-day moving average to forecast for the next day sales, the previous two days sales are taken , summed to up and finally averaged(that is divided by 2)

Next day forecast=sum of previous two days sales figures/number of days

sum of previous two days forecast=13+15=28

since the number of the days is 2 ,the 8 is divided by 2,28/2=14

Ultimately the next day forecast sales figure is 14 newspapers

Option A is wrong that is just considering of the two previous day, the same thing applies to option B.

Option C is the sum of previous two days sales without being divided
