2. A bank representative studies compound interest, so she can better serve
Kaylis [27]

Answer:

Step-by-step explanation:

Given that a  bank representative studies compound interest, so she can better serve  customers. She analyzes what happens when $2,000 earns interest several  different ways at a rate of 2% for 3 years.

a) the interest if it is computed using simple interest. 12.00

=\frac{2000(3)(12)}{100} \\=720 dollars

b) the interest if it is compounded annually.

=2000(1.12)^3-2000\\= 809.86 dollars

c) the interest if it is compounded semiannually

=2000(1.06)^6 -2000\\= 837.04

d) the interest if it is compounded quarterly.

=2000(1.03)^12 -2000\\= 851.52

e) the interest if it is compounded monthly.

=2000(1.01)^24 -2000\\= 861.54

An Internet store charges a base fee plus $1.50 per pound to ship items. The table shows samples of their shipping rates.
nalin [4]

Answer: For Last Question 4.50

Step-by-step explanation:It depends on the price per pound. Let's say the price per pound is 50 cents (or 0.50). (This is an example, the answer I'm giving will most likely NOT be correct, due to the nature of your question - sorry!) To calculate the price of Derek's package, you would multiply 7 (the weight of the package) by 0.50 (the price per pound), which totals to 3.50 Next, to calculate the price for Keisha's package, you'd do the same thing, but instead of multiplying 7 by the price per pound, you would multiply 10 by the price per pound, or 0.50. This multiplies out to 5 dollars. Next you'd subtract Derek's price from Keisha's, which is 5 - 3.50 or 1.50. If it is asking for a percentage, it would be about 150%.
