techniques in OPM $301,$ you wanted to

help your uncle forecast his sales for

the month of October. Based on the

sales data from January to September,

you found that this past data follows a

$176+2\mathrm{.}1t$; where $t$ is the index of the

month $($e$.$g$.$ for January, $t=1).$

Forecast the sales for the month of

October. Please round your answer to the

nearest integer. For example, if your answer is

$234\mathrm{.}56$ then type $235$ in the answer box.
