A Certain Company That Produces a Product with Seasonal Demands $y=14.25+0.25 x+2.8 \sin \left(\frac{\pi x}{6}\right)$

Short Answer

A certain company that produces a product with seasonal demands projects that monthly sales for the next two years can be modeled by $y=14.25+0.25 x+2.8 \sin \left(\frac{\pi x}{6}\right)$ . In the model, $y$ is the sales in thousands of units and $x$ is the time in months, with $t=1$ representing January, 2006. According to this model, what will be the projected sales for July $2006 ?$
