Diet. Table $3$ shows the per capita consumption of ice cream in the United States for selected years since $1987$.

(A) Let $x$ represent the number of years since $1980$ and find a cubic regression polynomial for the per capita consumption of ice cream.

(B) Use the polynomial model from part (A) to estimate (to the nearest tenth of a pound) the per capita consumption of ice cream in $2023$.
