Question

Suppose the expression a(b)n models the approximate number of customers who applied for a credit card every month since a bank opened, where a is the initial number of customers who applied, b is the rate of increase in the number of people who applied every month, and n is the number of months since the bank opened.

If the expression below models the number of applicants for a credit card, what is the correct interpretation of the second factor?

If the expression below models the number of applicants for a credit card, what is the correct interpretation of the second factor?

Answer 1

Answer:

$b \times n$ represents the increase in application of credit cards in n months.

Step-by-step explanation:

The expression $a + b \times{n}$ models the approximate number of customers who applied for a credit card every month(n) since the bank opened.

Therefore, we can write  $C= a + b \times{n}$ ....... (1) gives the perfect equation.

Now, for n=0, C = a which represents the number of customers who applied for credit card initially.

Therefore, the second term of equation (1) represents the increase in the application of credit cards in n months. (Answer)
