4.4 hours

Step-by-step explanation:

Let the number of hours be represented as h

The price of Stock A 9 AM was $12.71. Since then, the price has been increasing at the rate of $0.05 each hour

$12.71 + $0.05 × h

12.71 + 0.05h

At noon the price of Stock 8 was \$13.46 . To decrease at the rate of by $0.12each hour.

$13.46 + $0.12 × h

13.46 - 0.12h

If the two rates continue, in how many hours will the prices of the two stocks be the same?

12.71 + 0.05h = 13.46 - 0.12h

0.05h + 0.12h = 13.46 - 12.71

0.17h = 0.75

h = 0.75/0.17

h = 4.41176470588 hours

Approximately = 4.4 hours

The prices of the two stocks be the same in 4.4 hours
