Answer:

(a) $ 30000 + 1500 t

(b) $ 52500

Step-by-step explanation:

Initial profit = # 30,000

Profit increases every year by 5 %.

(a) Let the profit after t year is

P = $ 30,000 + 5% of 30,000 t  = $ 30000 + $ 1500 t

(b) t = 15 years

P = $ 30000 + $ 1500 x 15 = $ 52500  

Using exponential function concepts, it is found that:

a) The model is: [tex]A(t) = 30000(1.05)^t[/tex]

b) The prediction for her profits in 15 years is of $62,368.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

Item a:

  • Her business made $30,000 in profits the first year, hence [tex]A(0) = 30000[/tex].
  • Her annual profits have increased by an average of 5% each year since then, hence [tex]r = 0.05[/tex].

Then, the model is:

[tex]A(t) = A(0)(1 + r)^t[/tex]

[tex]A(t) = 30000(1 + 0.05)^t[/tex]

[tex]A(t) = 30000(1.05)^t[/tex]

Item b:

In 15 years, the estimate for the profits is of:

[tex]A(15) = 30000(1.05)^{15} = 62368[/tex]

The prediction for her profits in 15 years is of $62,368.
