Consider the data shown in the following table:

$\backslash$table$[[$Month$,$Sales$],[$January$,100],[$February$,200],[$March$,150],[$April$,400],[$May$,300]]$

Using an exponential smoothing model, the forecast for next June's sales is:

$450\mathrm{.}0$

Not enough information is given to make a forecast

$150\mathrm{.}0$

$477\mathrm{.}3$
