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

    Ft = 30 5.1t + 3t 2 where Ft = Unit sales t = 0 at the first quarter of last year

Explanation / Answer

Q1= 30- 5.1t+ 3t 2

Q1= 30-5.1*1.1+3*1.1*2= 30.99 units

Q2= 30- 5.1*1+3*1*2= 30.9

Q3= 30-5.1*0.6+3*0.6*2= 29.54 units

Q4= 30- 5.1*1.3+3*1.3*2= 31.17 units
