A large Portland manufacturer wants to forecast demand for a piece of pollution-control equipment. A review of past sales

(At),

as shown below, indicates that an increasing trend is present.Smoothing constants are assigned the values of

=

0.20

and

=

0.4.

The firm assumes the initial forecast for month 1

(F1)

was

9.00

units and the trend over that period

T1

was

2.00

units.

Using trend-adjusted exponential smoothing, Forecasts

(Ft),

Trend

(Tt),

and Forecasts Including Trend

(FITt)

for months 1 through 4 have already been developed and are provided below. Continue with the process and determine

Ft,

Tt,

and

FITt

for months 5 and 6 (round your responses to two decimal places):
