Answer:
<em>Student 2 is incorrect because he didn't use the formula properly</em>
Step-by-step explanation:
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.
Substituting into the formula:
C(3)=$216
Student 2 is incorrect because he didn't use the formula properly

Answer: 1350
Step-by-step explanation:
Here is the correct question.
Raquel can type an average of 63 words per minute. Rick can type 73 words per minute. how many more words can Rick type than Raquel in 135 minutes? Jared chose B as the correct answer. How did he get that answer? Jared said the answer is 4599. How did he get that answer?
Rick's word per minute= 73
Raquel's word per minute= 63
Ricks word in 135minute= 73×135 = 9855
Raquel's word in 135 minutes=63×135 = 8505
=9855 - 8505
= 1350
Rick can type 1350 more words than Raquel in 135 minutes.
Jared's answer is wrong. He got the answer by multiplying 63 by 73 which gives 4599.
