Final answer:

The total amount after 3 years of compounding $6000 at an annual interest rate of 10% would be closest to $7900, represented by option c in the multiple-choice answers.

Step-by-step explanation:

The student asked how much the total amount would be after 3 years if $6000 is invested in an account with 10% interest compounded annually. To solve this, we will use the formula for compound interest, which is A = P(1 + r/n)^(nt), where:

  • P is the principal amount ($6000)
  • r is the annual interest rate (0.10)
  • n is the number of times interest is compounded per year (1 for annually)
  • t is the time in years (3)

Plugging in the values:

A = $6000(1 + 0.10/1)^(1*3)

A = $6000(1 + 0.10)^3

A = $6000(1.10)^3

A = $6000 * 1.331

A = $7986

Hence, the total amount after 3 years will be closest to $7900, which is option c.
