Final answer:
The prices of the two stocks will be the same after 2.5 hours.
Step-by-step explanation:
To find the number of hours at which the prices of the two stocks will be the same, we need to set up an equation. Let's say x represents the number of hours since 9 am.
For stock A, the price at x hours is given by 15.95 + 0.11x.
For stock P, the price at x hours is given by 16.45 - 0.09x. Setting the two equations equal to each other, we have:
15.95 + 0.11x = 16.45 - 0.09x
0.20x = 0.50
x = 2.5 hours
ThErefore, the prices of the two stocks will be the same after 2.5 hours.
