The following equation summarizes the trend portion of quarterly sales of condominiums over a long cycle. Sales also exhibit seasonal variations. F_t = 62 5.2t + 4.2t ² where F_t = Unit sales t = 0 at the first quarter of last year

2	1.00
3	.65
4	1.30

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.)
