Lets first figure out what each of the words mean in symbols.

Three less: - 3
a number: x (you can use any variable, but the question says to use x)
five times a number: 5x
is 12: = 12

Now we need to put the equation together.

5x - 3 = 12 is the sequence that Danny wrote.

A pan is heated to 409°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 7

Answer: C. $265.9^{\circ}F$

Step-by-step explanation:

Given: The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.

$D = 338e^{-0.03t}$

At t= 8 minutes, we get

$D = 338e^{-0.03(8)}\\\\\Rightarrow\ D = 338e^{-0.24}\\\\\Rightarrow\ D = 338(0.786627861067)\\\\\Rightarrow\ D = 265.88\approx265.9^{\circ}F$

The approximate temperature of the pan after it has been away from the heat for 8 minutes= $265.9^{\circ}F$
