Answer:

500\leq 100(1.05)^t

Step-by-step explanation:

Given,

The initial deposit, P = $ 100,

Annual increasing rate, r = 5 %,

Thus, the amount after t years,

A=P(1+\frac{r}{100})^t

=100(1+\frac{5}{100})^t

=100(1+0.05)^t

\implies A = 100(1.05)^t

According to the question,

A ≥ $ 500

\implies 500\leq 100(1.05)^t

Which is the required inequality that can be used the value of t.
