C. $
755.80

Answer:

The amount of the interest is $755.80 .

Option (c) is correct .

Step-by-step explanation:

Formula

[tex]Amount = P (1 + \frac{r}{4})^{4t}[/tex]

Amount = Principle + Interest

Where P is the principle , r is the rate of interest in the decimal form and t is the time in years .

As given

Jason's savings account has a balance of $2179 .

The account is compounded quarterly at the rate of 6% for 5 years .

P = $2179

6% is written in the decimal form

[tex]= \frac{6}{100}[/tex]

= 0.06

r = 0.06

t = 5 years

Put all the values in the formula

[tex]Amount = 2179(1 + \frac{0.06}{4})^{4\times 5}[/tex]

[tex]Amount = 2179(1 +0.015)^{20}[/tex]

[tex]Amount = 2179(1.015)^{20}[/tex]

[tex]Amount = 2179\times 1.34686[/tex]

Amount = $ 2934.80 (Approx)

Thus

$2934.80 = $2179 + Interest

Interest = $2934.80 - $2179

Interest = $ 755.80

Therefore the amount of the interest is $755.80 .

Option (c) is correct .
