Hi, I need help solving for the six missing values. Thank you.

Transcribed Image Text:A large Portland manufacturer wants to forecast demand for a piece of pollution-control equipment. A
review of past sales (A₁), as shown below, indicates that an increasing trend is present. Smoothing
constants are assigned the values of α = 0.20 and ß = 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 (F₂), Trend (7+), and Forecasts Including
Trend (FIT+) for months 1 through 4 have already been developed and are provided below. Continue
with the process and determine F₁, T₁, and FIT, for months 5 and 6 (round your responses to two
decimal places):
