Question

Solve for the given variable
A= P (1+rt) for r

Answer 1

`r = (A-P)/(Pt)`

Explanation:

Step 1: Simplify both sides.

• 
  `A = P + Prt`

Step 2: Subtract P from both sides.

• 
  `Prt + P - P = A - P`
• 
  `Prt= A - P`

Step 3: Divide both sides by Pt.

• 
  `Prt/Pt= (A-P)/Pt`
• 
  `r = (A-P)/(Pt)`
