Is there another part to your question
Zero property because you are using zeros to multiply
$8250 - $3120 = $5130
$5130/75 = $68.40
Each band member must raise $68.40
When you have two unit prices for two comparable items, you have to convert one of the prices to the other one.
This is the concept of applications of polynomial equations. Given that the height of the ball is modeled by the function:
h(t)=16t^2-64t
the maximum height will be calculated as follows;
h(t)=16t(t-4)
therefore:
t=0 or t=4
h(4)=-64(4)+16(4^2)
=0
