The following equation summarizes the trend portion of quarterly sales of condominiums over a long cycle. Sales also exhibit seasonal variations.

Ft = 64 − 5.4t + 4.4t 2

where
Ft = Unit sales
t = 0 at the first quarter of last year

Quarter Relative
1 .90
2 1.10
3 .40
4 1.60


Using the information given, prepare a forecast of sales for each quarter of next year (not this year), and the first quarter of the year following that. (Round intermediate calculations and final answers to 2 decimal places.)
