To simplify this, we will use the Distributive Property. To use the Distributive Property, we multiply the number outside of the parenthesis by all inside numbers before adding.
2(x-4)
2(x) + 2(-4)
Multiply 2 by each number.
2x - 8 is your answer.
I hope this helps!

blsea [12.9K]

Answer:

The value of the CD at the end of the 4 years is $5,808.86.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Howard invested $5,000 in Certificate of Deposit (CD) that pays 3.75% interest.

This means that $P = 5000, r = 0.0375$
