Answer:

y= 4.3(4)^x

Step-by-step explanation:

I went to the Desmos Graphing calculator

I then inserted a table and added the two points you gave me to it

I then performed exponential regression to find the rate of change and y-intercept.

I then took the the two values and wrote the equation

A=y-intercept

B=rate

Lori buys a $400 certificate deposit that earns 1.8% interest compounded monthly how much will a cd be worth in six years
Firlakuza [10]

Answer:

$1445.11

Step-by-step explanation:

The formula to use would be:

F=P(1+r)^t

Where

F is the future amount (what we want to find)

P is the present (principal) amount (this is 400)

r is the rate of interest, monthly (1.8% or 0.018)

t is the time in months (6 years = 6 * 12 = 72)

Now substituting, we get:

F=P(1+r)^t\\F=400(1+0.018)^{72}\\F = 400(1.018)^{72}\\F=1445.11

After 6 years, the CD will be worth $1445.11
