Answer:

$t = \frac{100}{r} [\frac{D}{C} - 1]$

Step-by-step explanation:

Let’s consider that the amount deposited, C dollars, generates r% simple interest each year.

After a span of t years, the value of the deposited C dollars reaches D dollars; our task now is to formulate a relationship using these variables to find t.

We can express this relationship through the simple interest formula:

$D = C(1 + \frac{t\times r}{100})$

⇒ $1 + \frac{t \times r}{100} = \frac{D}{C}$

⇒ $\frac{t \times r}{100} = \frac{D}{C} - 1$

⇒ $t = \frac{100}{r} [\frac{D}{C} - 1]$

Thus, this yields the formula for t. (Answer)
