If $1500 is deposited in an account that pays 4% interest, what is the difference in the amount after 3 years between the amount earned if the principal is compounded annually and the amount earned calculated using simple interest? a.$3.20 b.$7.30 c.$9.40 d.$15.10

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 0.04%/100 = 0.0004 per year.

Solving our equation:

A = 1500(1 + (0.0004 × 3)) = 1501.8  

A = $1,501.80

The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 0.04% per year for 3 years is $1,501.80.

The answer is B. $7.30. I took this test btw, this is correct

Step-by-step explanation:

Compound interest:

1500(1 + .04)^3 = 1687.296

Ending principle - beginning principle = interest

1687.296 - 1500 = 187.296 (this is the interest for compound interest)

Simple Interest:

1500 * .04 * 3 = 180 (this is the interest for simple interest)

Subtract both interests to get the difference:

187.296 - 180 = 7.296 rounded equals 7.30

The answer is $7.30 :))

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
