Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast

This question is incomplete, the complete question is;

Given that a Historical Demand for a product is;

Month         Demand

January      12

February    11

March        15

April           12

May            16

June           15

Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast.

the July forecast is 15

Step-by-step explanation:

Given that;

Month       Demand          Weights

January      12

February    11

March        15

April           12                     0.10

May            16                     0.30

June           15                     0.60

July             ?                          ?

Formula for calculating weighted moving average is

Ft = w1A_t-1 + w2A_t-2 + wnA_t-n  

w1, w2, wn is the weight assigned to the period t-1, t-2, t-n respevtively

A_t-1, A_t-2, A_t-n is the demand period t-1, t-2, t-n respevtively

and n is the total number prior periods in the forecast.

so we just substitute our values into the equation

Forecast(July)  = (15 × 0.6) + (16 × 0.30) + ( 12 × 0.10)

= 9 + 4.8 + 1.2

= 15

Therefore the July forecast is 15

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

yes

step-by-step explanation:

yes
