Let P be the amount of invested money. Then, .08P = 336 P = 336/.08 = 4,200
If an amount C is invested for n years with an interest rate of r%, then the amount of interest earned is C*n*r/100
an investmntment of 4000 is made at an annual simple interest rate of 8%. How much additional money must be invested at 12% so that the total interest earned is 1640?
Simple interest = money invested x rate/100 x number of years
Two equations. x+y=56000 .07x=.05y Solve both of these equations simultaneously and it will be the answer. x+(.07/.05 x)=56000
It was eight years.
A $5000 investment at an annual simple interest rate of 4.4% earned as much interest after one year as another investment in an account that earned 5.5% annual simple interest. How much was invested at 5.5%?
Let P be the amount of invested money. Then, .08P = 336 P = 336/.08 = 4,200
7% of 3,000 for 6 month
If an amount C is invested for n years with an interest rate of r%, then the amount of interest earned is C*n*r/100
Kate invested 4500.
Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70Simple interest = 700*5/100*2 = 70
an investmntment of 4000 is made at an annual simple interest rate of 8%. How much additional money must be invested at 12% so that the total interest earned is 1640?
Simple interest = money invested x rate/100 x number of years
Simple intrest is one you are making on the principle. Compound Intrest is one your are making on principle plus intrest you have earned on it. So basically you are making Intrest on the Intrest you have earned on your principle. For Example: Compound Intrest, You have $5000.00 invested in a CD, First month you have earned $100.00 on that CD in intrest, in following month you will earn more because you are getting paid intrest on your $100.00 you have earned in intrest in first month and it goes on like that. in simple intrest you won't make intrest on intrest you have earned, you will only earn it on actuall $5000.00.
Two equations. x+y=56000 .07x=.05y Solve both of these equations simultaneously and it will be the answer. x+(.07/.05 x)=56000
Multiply the principal (P) by the annual* interest rate as a decimal (r) and the time in years* (t). *The time period may be expressed in months, etc. For example, $2000 invested at 7% simple interest for 5 years: I = Prt = 2000x0.07x5 = 140x5 = $700.
