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%?
Take the annual interest rate, divide it by 2 and multiply it by the amount you invested or borrowed.
Let P be the amount of invested money. Then, .08P = 336 P = 336/.08 = 4,200
Kate invested 4500.
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.
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.
p = principal ie amount invested; r = annual rate of interest; t = time in years. interest receivable = (p x t x r)/100
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 interest is computed on the principal amount, which is the initial sum of money borrowed or invested. It is calculated using the formula: Interest = Principal × Rate × Time, where the rate is the annual interest rate and time is the duration in years. Unlike compound interest, simple interest does not take into account any interest that accumulates on previously earned interest. Thus, it remains constant throughout the investment or loan period.
