The amount of simple interest accrued on a sum of money varies jointly with the amount of money, the interest rate, and the time the money is invested. a sum of money is invested at 4% for 3 years and accrues $168 in interest. the same sum of money is invested in a second account at 6% for 4 years. which statement is true?

which is the answer?

a )the amount of interest accrued on the second account is less than double the amount of interest accrued on the first account.

b )the amount of interest accrued on the second account is double the amount of interest accrued on the first account.

c ) the amount of interest accrued on the second account is more than double but less than triple the interest on the first account.

d ) the amount of interest accrued on the second account is more than triple the interest accrued on the first account.

B )The amount of interest accrued on the second account is double the amount of interest accrued on the first account.

Step-by-step explanation:

A sum of money is invested at 4% for 3 years and accrues $168 in interest.

Lets find the principle.

The formula for simple interest is =

p = ?

i = 168

r = 4%

t = 3

Now putting these values in the formula;

p = $1400

The same sum of money is invested in a second account at 6% for 4 years.

So, interest will be =

I = $336

Difference between both interests = dollars

We can see, that the second account gives double amount of $168.

Now, the true statement is :

B )The amount of interest accrued on the second account is double the amount of interest accrued on the first account.

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
