Simple interest i in dollars is calculated using the formula i=prt, where p represents the principal, or amount in dollars that is invested or borrowed; r represents the annual interest rate, expressed as a decimal; and t represents time, in years. find the value of the variable t, using the simple interest formula. i=$540, p=$4800, r=4.5 write the interest rate r as a decimal. r = ?

and we do this one the same way as the other.

Step-by-step explanation:

We have been given the formula to simple interest. We are asked to find the variable t using the given formula and given values.

Simple interest formula: , where,

= Amount of interest after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Given: , ,

Let us convert our given interest rate in decimal form.

Upon substituting our given values in simple interest formula, we will get:

Therefore, the value of t is 2.5 years.
