too much "C" and in the wrong direction.

P(t)=25sin(pi/12(t-6))+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.

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 $P(t)=95-25\cos\left(\dfrac{\pi}{12} \cdot t \right)$
