Valentina invested 6500 in a savings account with a yearly interest rate of 4% for 7 years. How much simple interest did she earn?
In order to find that all you do is multiply 6,500.047
And the simple interest is $1,820
Answer: She earned $ 1820 simple interest.
Step-by-step explanation:
Here, the principal amount, P = $ 6500,
Annual rate of interest, r = 4 %,
Time, t = 7 years,
Thus the simple interest earned in this amount,
\(S.I.=\frac{P\times r\times t}{100}\)
\(=\frac{6500\times 4\times 7}{100}\)
\(=\frac{182000}{100}=1820\)
Thus, she earned $ 1820 simple interest.
