Answer:

B. $5039.58

Step-by-step explanation:

compound interest formula: amount = p(1 + \frac{r}{n})^{nt}

p= principal ($2,300)

r= interest rate as a decimal (4% = 0.04)

n= number of times the principal is compounded per year (annually = onceper year so 1 time per year)

t= time in years (20 years)

new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}

That equation equals $2,739.58 which you add to the principal.

$2,739.58 + $2,300 = $5039.58

hope this helps :)

Answer:

x = (64 + 5) ÷ 3

Step-by-step explanation:

                                        3x - 5 = 64

Add 5 to both sides:            3x = 64 + 5 = 69

Divide both sides by 3:          x = 69 ÷ 3 = 23

So the answer is x = (64 + 5) ÷ 3

Note:  If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + \frac{5}{3} = 65 \frac{2}{3}
