Question

Using technology, we found that Mary's investment account can be modeled by the function M(t) = 4.96(1.282t), in thousands of dollars. What was Mary's initial investment?

Answer 1

4.96$

Every year she will gain 0.282 percent more.

Answer 2

Answer: $4,960

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*\$1000=\$4,960`

Therefore, the initial investment = $4,960
