\text{Hey there!}

\text{PEMDAS means: Parentheses, Exponents, Multiplication, Division, Addition}\\\text{, \& Subtraction}

\text{\underline{No}, it is \underline{NOT} correct because you had to work with the parentheses first}

\dfrac{8}{2}(2 + 2) = \ ? \\ \\ (2 + 2) = 4 \\ \\ \dfrac{8}{2}(4) = \ ? \\ \\ \dfrac{8}{2}= 4 \\ \\ \text{4(4)\ = 16} \\ \\ \boxed{\boxed{\huge\text{Answer should be: 16 }}}

\text{You had to do what was inside the parentheses first, then}\text{ divsion}

\text{Good luck on your assignment and enjoy your day!}

Two banks offer compound intereston your investment while you deposit with them. Bank A calculates compound interest annuallyand
sladkih [1.3K]

Answer:

Bank B because the more often you compound interest, the more interest you earn.

Step-by-step explanation:

Bank A compounds the interest once a year.

Bank B compounds the interest twice a year.

Let's create an example of two investments of the same amount of money, the same interest rate, and the same time. The only difference will be the number of times the interest is compounded per year.

Compound interest formula:

A = P(1 + \dfrac{r}{n})^{nt}

where

A = future value

P = principal invested

r = interest rate

t = number of years

n = number of times interested is compounded in 1 year

Example:

P = $1000

r = 5%

t = 5 years

Bank A: n = 1

Bank B: n = 2

Bank A:

A = $1000(1 + \dfrac{0.05}{1})^{1 \times 5} = $1276.28

Bank B:

A = $1000(1 + \dfrac{0.05}{2})^{2 \times 5} = $1280.08

Bank A's investment is worth $1276.28 after 5 years, but Bank B's investment is worth $1280.08 after the same 5 years. Compounding twice per year instead of only once per year earns more interest.
