Laura invests $3600 in a savings account for 2 years. The account pays 3.52% compound interest per annum. Laura has to pay 40% tax on the interest earned each year. The tax is taken from the account at the end of each year. How much is in the account at the end of 2 years?

$3753.64

Step-by-step explanation:

Initial amount = $3600

Interest rate = 3.52%

n = 1 (once in a year)

Time = 1 years

No of years = 2

Compound interest

 A =

   = $3726.72

                          =  $126.72

       =   = $50.69 (This amount is deducted from interest )

                                                     = $76

                                  = $3676

Similarly for the 2nd year

Compound interest

    A =

         = 3676(1.0352)

           =  $3805.4

                           = $129.4

       = $51.76

                                 = $77.64

                                               = $3753.64

step-by-step explanation:

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.
