Following are the data on demand for white bread loaves at a bakery.

a$.$ Develop a linear trend equation for the above data on demand for white bread loaves at a bakery $($use of Excel's Trendline, with

display Equation on chart option, is recommended$),$ and use It to forecast demand on day $16.($Round the final answers to $2$ decimal

places.$)$

$Y=$

$x+$

Forecast demand on day $16$

b$.$ The varlations around the linear trend line seem to have above$-$ and below$-$the$-$Ine runs. Therefore, use trend$-$adjusted exponentlal

smoothing with $=0\mathrm{.}3$ and $=0\mathrm{.}2$ to model the bread demand. Use the first four days to estimate the smoothed initial trend that you

use for periods $4$ and $5($use the Increase from day $1$ to day $4$ divided by $3).$ Also, use $A_4$ to estimate $S_4.$ Start forecasting day $5.$ What is

the forecast for day $16?($Round the final answers to $2$ decimal places.$)$
