What would be the value of $100 after 10 years if you earn 11 percent interest per year?

Answers

If the interest is simple interest, then the value is

   100 [ 1 + (10 x 0.11) ] = 100 (1 + 1.1) = 100 x 2.1 = $210 .

If the interest is compound interest, and is compounded annually,
then the value is

   100 (1 + 0.11)¹⁰ = 100 (2.8394) = $283.94 .

If the interest is compound interest, and is compounded monthly,
then the value is

   100 (1 + 0.11/12)¹²⁰ = 100 (2.9891) = $298.91 .

That's why compound interest is better than simple interest.

Answer:

$\left[\begin{array}{ccc}A&259.37\nB&283.94&Correct\nC&110.46\end{array}\right]$

Step-by-step explanation:

$\left[\begin{array}{ccc}100(1+(0.11)/(12))^(10) \end{array}\right] = \left[\begin{array}{ccc}100(2.8394)\end{array}\right] = \left[\begin{array}{ccc}283.94\end{array}\right]$

Answers

2) Your answer is correct. It is B. 70.9%
4) We can round 81.25% to 80 and 21 shots to 20. 20 x 0.8 = 16.
The answer is A. about 16
5) Your answer is correct. 48% is almost half; half of $20 is $10, so the answer is D.
6) Your answer is correct, C. 15% x 100 = $15
7) The proportion 50/100 = x/70 can help solve this. The answer will be 35.
8) We simply do:
15/50 x 100 = 3/10 x 100 = 30%
9) You are correct, C. 0.3 x 60 = 18
