Question $4$ options:

A manager is using the equation below to forecast quarterly demand for a product:

Yt $=6,000+80$t where t $=0$ at Q$2$ of last year

Quarter relatives are Q$1=\mathrm{.}6,$ Q$2=\mathrm{.}9,$ Q$3=1\mathrm{.}3,$ and Q$4=1\mathrm{.}2.$

What forecasts are appropriate for the last quarter of this year and the first quarter of next year?

Hint: t $=0$ at Q$2$ of last year so t$=5$ for Q$3$ of this year.
