P(t)=25sin(pi/12(t6))+95 is correct. When you do P(12) It equals 120. My question is how did you immediately know that 6 shifted the graph correctly and that 6 was c? Thanks for your help. Last edited by HisNameForever; December 4th, 2016 at 08:01 PM.

The green graph is the sine curve with no shift ... note the red curve is that green sine curve shifted right 6 hours. btw ... the equation of the red curve can also be written $P(t)=9525\cos\left(\dfrac{\pi}{12} \cdot t \right)$
