Help, please. A museum charges a $6 admission fee for every person (btw there's 4 people). Write an equation to represent the relationship between the number of people x, and the total collected, y.

The motion of a weight that hangs from a spring is represented by the equation h=8sin(2pi/3t). it models the weight’s height above or below the rest position as a function of time. approximately when will the object be 3 inches above the rest position?
