Answer 1

Answer:  $4,960

Step-by-step explanation:

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

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

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

Therefore, the initial investment = $4,960

Answer 2

4.96$

Every year she will gain 0.282 percent more.
