I = PTR/100. In this case I = 3225, P = 4300, T is unknown and R = 4.
so 3225 = (4300 x T x 4)/100 ie 3225 = 172T making T = 18.75, so it'll be 3/4 of the way throught the nineteenth year.

1200 rate*money invested*interest(divided by a 100) 5*4000*.06=1200
The formula for simple interest is Interest = Principal x Rate x Time ÷ 100 As the rate is an annual rate and the period is 1 year then Interest = Principal x 4.5/100. The balance at the year end = Principal + Interest = Principal x 104.5/100.
This answer is False!!
6% of $4,000 = $240 .If it's paid 5 times, he receives (240 x 5) = $1,200 .

You have confused between the terms. Simple interest and interest at flat rate is one and the same. The other type of interest is diminishing balance or reducing balance. These are interests associated with loans or finances sought. Well a simple rule of thumb is that usually simple interest rate is about half of rate on reducing balance. For e. g. if rate at reducing balance is 12% then simple interest for the same will be around or just more than 6%
This answer is False!!

Simple interest would be 360
Simple interest would be 1040
