Pat deposits $600 in a savings account at a simple interest rate 6% per year for 5 years. How much money will Pat have earned in interest at the end of 5 years?

A. $360

B. $180

C. $95

D. $36

Answer Explanation:

In the simple interest, we utilize the following formula to find the simple interest after a period of time in years.

I=P*r*t

I is the interest

P=Principal or initial deposit

r=rate

t=time in years

From the given problem, P=$600, r=6%=6/100=0.06, t=5 years. Then

I=$600*0.06*5=$180

After 5 years, Pat will earn an interest of $180.

Therefore, the Correct Answer is B.

  • Q #2: 7x - 6= 3x - 26 Solve the equation above for x. Which of the following is the value for x?

    A. -5

    B. 6

    C. 5

    D. -8

    Answer Explanation

    Here we collect like terms together and solve for the unknown value of x.

    7x-6=3x-26

    Add 6 to both sides of the equation

    7x-6+6=3x-26+6

    7x=3x-20

    Subtract 3x from both sides of the equation

    7x-3x=-20

    4x=-20

    Divide both sides by 4

    4x/-4=-20/4

    x = -5

    The value of x = -5
