Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. david invested $220 in a savings account that offers a 3% return on the investment. the value of david's investment will be at least $400 after a period of years. hint: use the formula a = p(1 + r)t, where a is the amount after t years, p is the amount invested, r is the rate of interest, and t is the time period. use a calculator to compute the answer, and round it off to the nearest year.

The answer is 23 years.

Step-by-step explanation:

We will use the formula :

Here P = 220

r = 3%

A = 400

Putting these values in the formula we get,

Taking log on both sides,

ln(1.03)t=ln 2

t=23.44 or rounding to nearest, t=23 years

The graph of the function can be shown as below.

there is no picture

step-by-step explanation:

put up a picture so people can you

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
