Consider the following Monthly time series data and Apply Holt's model to the forecast ( Carry on up to 3 decimal points: e.g., 3.215)

Time	February	March	April	May	June
Demand	350	370	400	470	550

Determine L_0 and T_0 based on the given data. (Use Excel: 2 points) b) Predict demand for February using Holt's model with =0.3,=0.6. (2 points: Don't use an Excel computer, Show your work using an equation) d) Predicted demand for March using Holt's model with =0.3,=0.6. (4 points: Don't use an Excel, Show your work using an equation)
