Marilyn uses a credit card with a 19.9% APR compounded monthly to pay for car repairs totaling $991.38. She can pay $410 per mon
Leokris [45]
Marilyn's finance charge at the end of the first month will be
  $991.38 × 0.199/12 = $16.44
The balance subject to the next month's finance charge will be
  $991.38 +16.44 -410.00 = $597.82

The finance charge at the end of the second month will be
  $597.82 × 0.199/12 = $9.91
The balance remaining after the second payment will be
  $597.82 +9.91 -410.00 = $197.73

The finance charge applied at the end of the third month is
  $197.73 × .199/12 = $3.28
so Marilyn can make one final payment of
  $197.73 +3.28 = $201.01
to pay off the balance.

In all, Marilyn has paid 2×$410.00 +201.01 = 
  $1021.01 . . . . . . . . corresponds to the first choice

_____
In real life, Marilyn's credit card may not accrue any finance charge until after the first statement on which the charge appears. Thus the total cost of the purchase may be only $1004.02. The attached spreadsheet shows the beginning balance and the finance charges for each month for the two different scenarios.

The mean of a set of data is -3.82 and its standard deviation is 2.31. Find the z score for a value of 3.99.
gtnhenbr [62]

Answer:

The z- score for a value of 3.99 will be 3.38.

Step-by-step explanation:

It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.

Thus, the value of the z-score=\frac{value-mean}{standarddeviation}

=\frac{3.99-(-3.82)}{2.31}

=\frac{3.99+3.82}{2.31}

=\frac{7.81}{2.31}

=3.38

Thus, the z- score for a value of 3.99 will be 3.38.
