Marvin currently has a balance of $1192 in an account he has held for 14 years. he opened the account with an initial deposit of $800. what is the simple interest on the account?
a. 2.3%
b. 3.5%
c. 7.1%
d. 10.6%

Option B. 3.5%

Step-by-step explanation:

Marvin currently has a balance of $1192 in his account. He opened the account with an initial amount of $800.

Duration for which the amount was held = 14 years

we have to calculate the rate of interest

Since Simple interest =

Interest = Final amount - initial amount

Interest = 1192 - 800

             = $392

Now we plug these values in the formula

392 =

392 =

R =

   = 3.5%

Option B is the answer.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
