The sommers invested $5000 for three years at 6.5%. how much interest did the investment earn in three years? what was the total amount of the account after three years?

answer:

the interest is $975 the total amount   is $5975

step-by-step explanation:

lets use the formula i=prt where i is interest earned p is the principal amount(original amount)r is the rate of interest and t is the time in years

so the principal amount is 5000 since it is the original amount rate is =0.065time is 3 years

lets plug these values into our equation: 5000*0.065*3=i5000*0.065*3=975the interest is $975

the next part of the question is asking for the balance or the total amount which is principal+interest5000+975=5975

the total amount or balance is $5975
