Homework Help: Math

Posted by Samantha on Thursday, October 25, 2007 at 2:31pm.

I don't get either of these equations. Please help me out!

1. Music Mart sells an average of 150 cassette tapes daily at $10.00 a tape. If 15 sales are lost for each $0.50 increase in unit price, what price will maximize profits? What will be the resulting daily profit?

2. S. Piker served a volleyball from 1 meter off the ground with an initial upward velocity of 8 meters per second. Write an equation for the height of the ball "h" in meters after "t" seconds. What will be the height of the ball after .5 seconds? What is the maximum height of the ball? If no one touches the ball, when will it hit the floor?
