a. Using a weighted moving average with weights of 0.50 (June), 0.30 (May), and 0.20 (April), find the July forecast. (Round your answer to 1 decimal place.)

This question is incomplete, the complete question is;

Given the Historical demand for a product;

                  DEMAND

January       19

February     18

March          22

April             19

May              23

June             22

Using a weighted moving average with weights of 0.50 (June), 0.30 (May), and 0.20 (April), find the July forecast. (Round your answer to 1 decimal place.)

the July forecast is 21.7

Step-by-step explanation:

Given the data in the question;

July forecast will be;

(june × weight) + ( may × weight ) + ( april × weight)

so

July Forecast = (22 × 0.50) + (23 × 0.30) + (19 × 0.20)

July Forecast =  11 + 6.9 + 3.8

July Forecast = 21.7
