Sagot :

In this problem

we have an exponential growth function of the form

[tex]y=a(1+r)^x[/tex]

where

y is the total amount in the saving account

x is the number of years since the year 2013

r is the rate

a is the initial value

where

a=$15,500

r=4.4%=4.4/100=0.044

year 2031 -----> x=2031-2013=18 years

substitute in the equation

[tex]\begin{gathered} y=15,500(1+0.044)^{(18)} \\ y=\$33,646.56 \end{gathered}[/tex]
