If Lily chooses account A, the balance of her account would increase by a rate of 2.4%  on a quarterly basis

The Equation

The equation of the function is given as:

[tex]A(t) = 3000(1.024)^{4t[/tex]

Exponential function

An exponential function is represented as:

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

Where:

  • a represents the initial value
  • r represents the rate

So. by comparison:

[tex]1 + r=1.024[/tex]

Subtract 1 from both sides

[tex]r=.024[/tex]

Express as percentage

[tex]r=2.4\%[/tex]

From the function, the exponent of the rate is 4t.

This means that, the balance increases four times in a year.

So, her balance would increase quarterly
