Youll often find the formula written using an annual interest rate where the number of periods is specified in years or a fraction of a year.
I=prt how to solve. According to this formula the amount of interest is given by I Prt where P is the principal r is the annual interest rate in decimal form and t is the loan period expressed in. These are designated by the variables p for the principal or the amount of money borrowed r for the interest rate and t for the length of time. R Rate of Interest per year in decimal.
Rewrite the equation as prt I p r t I. Add your answer and earn points. Interest I Principal P times Rate Per Period r times Number of Periods n Divide an annual rate by 12 to get r if the Period is a month.
You can put this solution on YOUR website. Finally P will be. You need to solve for I I PRT I 1 5009 10021 12 23625 Therefore Martha will receive R23625 in interest at the end of the period Note how the term of 21 months is treated ie.
Simplifying i prt. P Principal Amount. .
Divide both sides by pr. The given equation is I prt. Solution for iprt equation.
T Time Periods involved. After this as rt is part of the product with P all equality is divided by rt. IPrt To solve for r we divide both sides of the equation by Pt to isolate the r.
Tap for more steps. The simple interest formula allows us to calculate I which is the interest earned or charged on a loan. When the period is quoted in terms of months you would do the.
Tap for more steps. IPrt solve for t. P rt i P r t i Divide each term by P r P r and simplify.
According to this formula the amount of interest is given by I Prt where P is the principal r is the annual interest rate in decimal form and t is the loan period expressed in. To solve I prt multiply the amount of money borrowed by the interest rate and length of time. First of all we change the terms from one side of equality to another.
I Interest Amount. Divided both sides by P and r to isolate the variable t. Diving by 12 since there are 12 months in a year.
RIPt Solve for r. I p r t. The simple interest formula allows us to calculate I which is the interest earned or charged on a loan.
Prt I p r t I Divide each term by pt p t and simplify. R Rate of Interest per year as a percent. Simplifying i prt Solving i prt Solving for variable i.
Answer by prince_abubu 198 Show Source. Mathtut 3670 You can put this solution on YOUR website. When you know the principal amount the rate and the time the amount of interest can be calculated by using the formula.
Base formula written as I Prt or I P r t where rate r and time t should be in the same time units such as months or years. For the above calculation you have 450000 to invest or borrow with a rate of 95 percent for a six-year period of time. Move all terms containing i to the left all other terms to the right.
I prt is the formula for simple interest. Rewrite the equation as P rt i P r t i. I prt How to solve to get r 1 See answer thompkins732 is waiting for your help.
