Question

 The price of Stock A at 9 A.M. was ​$14.15. Since​ then, the price has been increasing at the rate of ​$0.06 each hour. At noon the price of Stock B was ​$14.65. It begins to decrease at the rate of ​$0.08 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answer 1

Answer:

2 hours

Step-by-step explanation:

Easiest way to solve this is add and subtract till we get the values balanced.

Stock A

9 am $14.15

10 am $14.21

11 am $14.27

12 pm $14.33

1 pm $14.39

2 pm $14.45

Stock B

12 pm $14.65

1 pm $14.57

2 pm $14.45

Notice the bold values are the same at the same time 2 pm. If we start at 12 pm with stock B, it will be 2 hours before the prices are the same.

I'm always happy to help :)
