Table 104 -Use the Information in Table 10 $A_{t}=W_{1} D_{t}+W_{2} D_{t}-1+W_{3} D_{t}-2 ^{A_{t}}=W_{1} D_{t}+W_{2} D_{{t}_{-1}}+W_{3} D_{{t}_{-2}}$

Table 10.4
$$\begin{array} { | l | c | } \hline { \text { Month } } & \begin{array} { c } \text { Actual } \\\text { Sales }\end{array} \\\hline \text { Tanuary } & 23 \\\text { February } & 18 \\\text { March } & 22 \\\text { April } & 28 \\\text { May } & 24 \\\hline\end{array}$$
-Use the information in Table 10.4.The forecasting equation for a three-month weighted moving average is:
$A_{t}=W_{1} D_{t}+W_{2} D_{t}-1+W_{3} D_{t}-2 ^{A_{t}}=W_{1} D_{t}+W_{2} D_{{t}_{-1}}+W_{3} D_{{t}_{-2}}$

If the sales for June were 40 units and the weights are W?= 1/2,W? = 1/3,and W? = 1/6,what is the forecast for July?

A) less than or equal to 30 units
B) greater than 30 but less than or equal to 33 units
C) greater than 33 but less than or equal to 36 units
D) greater than 36 units
