The company’s sales for year 2015, 2016, 2017, and 2018 were 50,000, 60,000,65,000 and 75,000 respectively. Determine the sales forecast for the year 2019 using (a) four years moving average ?

To calculate the four-year moving average, we need to take the average of the sales for the current year and the three previous years.

For the year 2019, we will take the average of the sales for 2016, 2017, 2018, and 2019.

Sales for 2016: 60,000
Sales for 2017: 65,000
Sales for 2018: 75,000
Sales for 2019: ?

Sales forecast for 2019 = (60,000 + 65,000 + 75,000 + 2019) / 4

To find the value of sales for 2019, we can rearrange the equation:

2019 = (Sales forecast for 2019 * 4) - (60,000 + 65,000 + 75,000)

Now we can substitute the given values:

2019 = (Sales forecast for 2019 * 4) - (200,000)

Rearranging the equation:

Sales forecast for 2019 * 4 = 2019 + 200,000

Sales forecast for 2019 * 4 = 201,019

Sales forecast for 2019 = 201,019 / 4

Sales forecast for 2019 = 50,254.75

Therefore, the sales forecast for the year 2019 using the four-year moving average is approximately $50,254.75.
