Question

The price of Stock A at 9 AM WAS $12.24. Since then, the price has been increasing at

the rate of $0.11 each hour. At noon the price of Stock B was $12.74. It begins to decrease at the
rate of $0.15 each hour. If the two rates continue, in how many hours will the prices of the two
stocks be the same?

Answer 1

Explanation:

t is the number of hours

12.24+0.11t = 12.74-0.15t

0.11t + 0.15t = 12.74 - 12.24

0.26t = 0.5

t= 0.5/0.26

t= 1.92 hours

approx to 2 hours
