simple interest is I = prt so rate becomes r = I / (pt)
r = 76 / (800 x 2) = 76/1600 =0.0475
if you need a percent answer multiply by 100
r = 4.75 percent

Use the formula I = P x R x TWhere I=interestP=principal investmentR=interest rateT=time in yearsIn this case, we want to know R, so re-arrange the formula to get:R = I / (P x T)=456/ (1600x6)=456/9600=0.0475=4.75%
Oh, dude, it's like super simple math. So, to calculate the principal amount P, you just divide the interest by the interest rate times the number of years. In this case, 40 divided by (10% times 5 years) gives you the principal amount P. That's like, what, 80 bucks? Math is fun, right?
3% for 4 years is equivalent to 12% of the principal, in this case 12 x 9.5 which is 114.
6.5%Formula for finding Simple InterestSI [Interest] = (P×R×T)/100P [sum] = (SI×100)/(R×T)R [Rate/year] = (SI×100)/(P×T)T [Time] = (SI×100)/(P×R)whereS.I. = Simple Interest,P = Principal or Sum of amount,R = % Rate per annum,T = Time Span
Assuming that 1.5 refers to 1.5% and that the interest is compounded annually, the principal is 893.30
Interest for 1st year = $6 Principal after 1 year = $206 Interest for 2nd year = $6.18 Principal after 2 year = $212.18 Total Interest earned after 2 years = $12.18
To calculate the interest earned in one year, you can use the formula: Interest = Principal × Rate × Time. Here, the Principal is the initial amount of money invested or borrowed, the Rate is the annual interest rate (expressed as a decimal), and Time is the duration in years (which is 1 for one year). For example, if you have a principal of $1,000 and an annual interest rate of 5%, the interest earned in one year would be $1,000 × 0.05 × 1 = $50.
The amount, P, is the principal. If the rate is r% compounded annually for y years, then the total interest earned is P*[(1 + r/100)^y - 1]

P*(1+R/100)powerT where P= money borrowed or principal and R= rate in percent and T= time * * * * * Actually, this formula gives the value of the principal PLUS interest. You need to subtract P from the answer to get the compounded interest.
To calculate the interest earned on $3,000 at a 7% annual interest rate over 4 years, you can use the formula for simple interest: Interest = Principal × Rate × Time. Plugging in the values: Interest = $3,000 × 0.07 × 4, which equals $840. Therefore, the total interest earned would be $840 over the 4-year period.
It is 5%.
The amount of money multiplied by the interest rate and the amount of time it earns interest represents the interest earned over that period. This can be expressed using the formula: Interest = Principal × Rate × Time, where the Principal is the initial amount of money, Rate is the interest rate (as a decimal), and Time is the duration in years. This calculation is fundamental for understanding simple interest in finance.

Compound interest is calculated on the initial principal plus any accumulated interest, resulting in interest earning interest over time. Normal interest, on the other hand, is only calculated on the initial principal amount and does not take into account any interest that has already been earned.
To calculate the simple interest earned on Susan's savings account, use the formula: Interest = Principal × Rate × Time. Here, the principal is $800, the rate is 6% (or 0.06), and the time is 5 years. Therefore, Interest = 800 × 0.06 × 5 = $240.00. The correct answer is C) 240.00.
