<u>Modeling of Reality</u>

Sometimes we have a real situation and we want to provide a mathematical model to explain it. But what if we have the model and need to imagine what the situation could be? It calls for our imagination and tries to figure out such a problem, given the answer

We can see a question mark multiplying the fraction 1/8 to produce a result of 3. This is a common proportion problem. This is my approach

"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "

If we solved this question, we have to replace the ? for 24 and say Peter sold 24 pencils and made 24(1/8)=$3

Answer:

First one: 5x3(0.75)2t

and fourth one: 0.05x500(0.005)t

Step-by-step explanation:

In order to have an exponencial decay, the rate of the exponencial function needs to be lesser than 1.

The rate is the value between parenthesis, so in the first equation, the rate is 0.75, so this is an exponencial decay.
