Question

Camryn puts $400 into a savings account that earns 6% annually. the amount in her account can

Answer 1

The exponential function that approximates the amount of money in her account using a weekly growth rate is:

$c_w(t) = 400(1.001154)^{\frac{t}{52}}$

What is an exponential function?

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

• A(0) is the initial value.

• r is the growth rate, as a decimal

In this problem, the yearly function is:

$c(t) = 400(1.06)^t$

Considering that a year has 52 weeks, we have that:

0.06/52 = 0.001154

Hence:

$c_w(t) = 400(1.001154)^{\frac{t}{52}}$
