Question

The price of Stock A at 9 A.M. was​ $15.75. Since​ then, the price has been increasing at the rate of​ $0.05 per hour. At​ noon, the price of Stock B was​ $16.53. It begins to decrease at a rate of​ $0.13 per hour. If the stocks continue to increase and decrease at the same​ rates, in how many hours will the prices of the stocks be the​ same?

Answer 1

the price of Stock A and Stock B will be the same after 3.5 hours.

Explanation:

15.75 + (0.05 × 3) = 15.90

15.90 + 0.05t= 16.53 - 0.13t

0.05t + 0.13t = 16.53 - 15.90

0.18t = 0.63

t = (0.63 ÷ 0.18)

t = 3.5
