Question 1073054
The price p in dollars for a particular stock can be modeled by the quadratic equation p = 3.5t^2 .05t, where t represents the number of days after the stock is purchased.
 When is the stock worth $60?
:
P=60, assuming it is +.05
3.5t^2 + .05t = 60
3.5t^2 + .05t - 60 = 0
Using the quadratic formula
t ~ 4 days
