Answer 2

Option (c) $7,672

Step-by-step explanation:

Data provided in the question:

Investment amount i.e principle = $9,875

Interest rate,r = 4.8%

Time, t = 12 years

Now,

Future value = Principle ×
`\left( 1 + (r)/(n) \right)^{\Large{n \cdot t}}`

n = number of times compounded per year

Future value =
`= 9875*\left( 1 + ( 0.048 )/( 12 )\right)^{\Large{ 12 \cdot 12 }}`

Future value =
`9875*{ 1.004 } ^ { 144 }`

Future value =
`9875*1.776866`

Future value = $17,546.55

Also,

Future value = Principle + Interest

Therefore,

$17,546.55 = $9,875 + Interest

or

Interest = $17,546.55 - $9,875

= 7671.55 ≈ $7,672

Hence,

Option (c) $7,672
