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.

Given:
Volume of Large cube = 1 cubic unit
Volume of small cube = cubic unit
To find:
The difference between the edge length of the large cube and the edge length of the small cube.
Solution:
Let the edges of large and small cubes are and
respectively.
We know that, volume of a cube is
Volume of Large cube = 1 cubic unit
Taking cube root on both sides, we get
So, edge of large cube is 1 unit.
Volume of small cube = cubic unit
Taking cube root on both sides, we get
So, edge of large cube is unit.
Now, difference between them is
Therefore, the difference between the edge length of the large cube and the edge length of the small cube is unit.
