Answer:
If only it were that easy. After 1.44 hours, the price of the two stocks will be the same, 16.62.
Step-by-step explanation:
Let t be the time (in hours) after noon.
Stock(A) = 16.09 + 0.12 (t +3)
Stock(B) = 16.84 - 0.15t
Stock(A) = Stock(B)
16.09 + 0.12 (t+3) = 16.84 - 0.15t
16.09 + 0.12t + 0.36 = 16.84 - 0.15t
0.27t = 0.39
t=1.44 hours

Answer:

Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was
on Monday. So the decrease in temperature from Monday to Thursday will be
.
We have been given that the swimming pool is open when the high temperature is higher than
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:

Therefore, the inequality
can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
