the formula for the future value w of a simple interest investment is w = d + dst, where d is the original investment, s is the annual interest rate, and t is the time in years. solve this formula for t.

the formula for the future value w of a simple interest investment is w = d + dst, where d is the original investment, s is the annual interest rate, and t is the time in years. solve this formula for t.

Answer

Explanation:

Step1: Isolate the term with t

Subtract D from both sides of the equation $W = D+Dst$. $W - D=Dst$

Step2: Solve for t

Divide both sides of the equation $W - D = Dst$ by $Ds$ (assuming $D\neq0$ and $s\neq0$). $t=\frac{W - D}{Ds}$

Answer:

$t=\frac{W - D}{Ds}$
