10 years. Compound interest would take 7 years.
It will take 20 years.
To calculate an interest (as money), multiply the capital, times the interest rate (divided by 100, if it is expressed in percent), times the number of periods. The above assumes simple interest; compound interest is a bit more complicated.
A simple interest rate of 10 per cent per year will double a sum of money in ten years.
"How much money should be deposited at 4.5 percent interest compounded monthly for 3 years?"Incomplete question.... to do what?
it depends on wheather the interest is simple or compound also you should tell me how much money you put in the bank to begin with but lets calculate the interest on one dollar : if it is simple interest then: I=P*R*T where T is in years =1*18/100*1/360 interest on one dollar principal is 0.0005 $ if it is compound interest then: I= P*(R+1)^T-p =0.00046 which is about the same as the simple interest one multiply my answer by the amount that you put into the bank origonally to find out ur interest hope i helped
30 years
20 YEARS
if its simple interest: I = prt = 240 the total money to be returned is 2240
Two and a half percent of 750 ie 2.5 x 7.5 which is 18.75
7.5 x 2.5 ie 18.75
It will take 20 years.

simple interest = principle (money) times the rate times the time
1200 rate*money invested*interest(divided by a 100) 5*4000*.06=1200
Simple Interest
You earn more money using compound interest than simple interest because compound interest calculates interest on both the initial amount and the accumulated interest, leading to faster growth of your money over time.
Simple: 160 + (1.6 x 4 x 2) = 172.80 Compound: 160 x (1.04)2 = 173.06
