The price of Stock A at 9 A. M. was $12.79 Since then, the price has been increasing at the rate of $0.11 each hour. At noon the price of Stock B was $13.29 It begins to decrease at the rate of $0.12 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same? pls pls pls

2.174 hours

Step-by-step explanation:

Let the number of hours be represented as:

x

The price of Stock A at 9 A.M. was $12.79 Since then, the price has been increasing at the rate of $0.11 each hour.

$12.79 + $0.11 × x

12.79 + 0.11x

At noon the price of Stock B was $13.29 It begins to decrease at the rate of $0.12 each hour.

$13.29 - $0.12× x

13.29 - 0.12x

Equating both equations together

Stock A = Stock B

12.79 + 0.11x = 13.29 - 0.12x

Collecting like terms

0.11x + 0.12x = 13.29 - 12.79

0.23x = 0.5

x = 0.5/0.23

x = 2.1739130435 hours

x = Approximately = 2.174 hours

If the two rates continue, the number of hours that the prices of the two stocks will be the same is 2.174 hours

but there’s no any figure there!
