%rate= (55 ÷ 500) x 100% = 11%
Any positive rate of interest - as long as you leave the money invested for long enough.
The simple interest rate of a number is represented by the following formula: i = (T / P) - 1 Where: i = interest rate T = total of all payments P = principal amount For example, what is the interest rate if I borrowed $500 and paid back $50 per month for a year? T = $50/month * 12 months = $600 P = $500 i = (600 / 500) -1 i = 1.2 - 1 = 0.2 = 20% The simple interest rate is 20%.
Interest rate (also called the rate of return). For example: What is the interest rate on a 10,000$ principle investment that pays 500$ after one year? 10000 * r = 500 r = 500 / 10000 r = .05 = 5% Check: 10000$ @ 5%/1 yr = i 10000 * 5/100 = i 10000 * .05 = 500 ($ Interest at the end of 1 yr) 500 = 500 = true! ======== Response 1: what is the answer d. percent of change

500 principal, 10 percent annual rate => 50 annual interest 2 year => 100 total interest.
there is about 500
55% of 500= 55% * 500= 0.55 * 500= 275
$500 if interest for five years at a 7% interest rate
I don't know nor do I care
Use the equation I= Prt P= Principal amount(starting)r= Rate as a decimalt=timeI = (55)(0.04)(5)= 11Therefore, he will earn $11 in interest after 5 years.
