The Answer of The projected monthly sales (in thousands of units) of lawn mowers (a seasonal product) are modeled by 
 $S = 71 + 3 t - 40 \cos \left( \frac { \pi t } { 6 } \right)$  
Where t is the time (in months), with t = 1 corresponding to January.Select the graph of the sales function over 1 year.

The Projected Monthly Sales (In Thousands of Units) of Lawn S=71+3t−40cos⁡(πt6)S = 71 + 3 t - 40 \cos \left( \frac { \pi t } { 6 } \right)S=71+3t−40cos(6πt​)

The Projected Monthly Sales (In Thousands of Units) of Lawn $S = 71 + 3 t - 40 \cos \left( \frac { \pi t } { 6 } \right)$
