1. Given the following, determine the expected sales on September 18th and September 19th, using a 3-day weighted moving average.

2. Is your weighted moving average result higher or lower than if you had simply done a 3-day moving average? What caused it to be higher or lower?

\begin{tabular}{|c||c|c|c|} \hline MONTH & DATE & ACTUAL SALES IN DOLLARS & W1 =10 W2=25 W3=30 \\ \hline \hline SEPTEMBER & 12 & $1,500 & \\ \hline \hline & 13 & $2,500 & \\ \hline \hline & 14 & $2,500 & \\ \hline \hline & 15 & $3,500 & \\ \hline \hline & 16 & $3,000 & \\ \hline \hline & 17 & $4,500 & \\ \hline \hline & 18 & & \\ \hline \hline & 19 & & \\ \hline \end{tabular}
