Respuesta :

4.96$

Every year she will gain 0.282 percent more.

Answer:  $4,960

Step-by-step explanation:

Given: Using technology, we found that Mary's investment account can be modeled by the function [tex]M(t) = 4.96(1.282)^t[/tex]in thousands of dollars.

To find the initial investment we put the value t = 0, we get

[tex]M(0)=4.96(1.282)^0=4.96\text{ thousands of dollars}\\\\=4.96\times\$1000=\$4,960[/tex]

Therefore, the initial investment = $4,960
