2018年5月15日 · The idea here is to isolate the prt onto one side of the equation and then solve for r: Add prt to both sides: # A+ prt = p - prt + prt # #A + prt = p# subtract A from both sides #A-A + prt = p-A# #prt = p-A # Now that prt is isolated, you can solve for r. Divide both sides by pt (restriction #pt \ne 0 #) #\frac{prt}{pt} = \frac{p-A}{pt}#

A = P + Prt. The greatest common factor on the right side is P. Factoring it out results in the equation becoming:. A = P(1 + rt). Although it doesn't directly say so, the problem implies that the 15% simple interest rate is an annual rate. This means that r = 15% or equivalently, r = 0.15. And t is the time in years. The problem tells you that ...

After applying the distributive law, we get A = P + Prt. We now subtract P from A on the left side. This is what the equation looks like now: A - P = Prt On the right side, we have P*r*t or simply Prt. To finally isolate little r, divide both sides of the equation by Pt. Final answer: (A - P)/Pt = r

Question 777433: Using the formula B=P+Prt Suppose an account earns 5.5% interest and after two years the balance is $3330. Find the principal that was invested. So far I have 3,330= P+P(.55)(2) but I can't figure out what i'm doing wrong and my book isn't helping :/ Answer by stanbon(75887) (Show Source):

2016年3月5日 · The equation #A=p+prt#, represents amount receivable / payable #A#, after a period of #t# years, when a principal amount #p# is invested / borrowed at an annual (as time is in years) simple interest rate of #r#. Note that #prt# represents the simple interest. As such #t# is equivalent to the time period, for which the amount is borrowed or ...

2016年5月11日 · t = (a - p)/(pr) Rewrite the formula so that the term with t is positive on the left hand side. Isolate the term, then step by step, isolate the variable you want as the subject. p + color(red)(prt) = a color(red)(prt) = a - p " ""get rid of +p by -p" prcolor(red)t = a - p" " " get rid of x pr by ÷ pr" t = (a - p)/(pr)
