Answer:
Rounded to the nearest dollar, Bob saved $677 by buying the carpet on Wednesday.
Step-by-step explanation:
Since on Tuesday, Bob brought home an oriental carpet on approval and the price in the store was 9900 Turkish Lira, but Bob was going to pay in dollars and, on Tuesday, one dollar was worth 4.5 Turkish Lira but on Wednesday, the Turkish Lira was devalued such that one dollar was now worth 6.5 Turkish Lira, with which Bob then bought the rug on Wednesday, paying the price of 9900 Turkish Lira with dollars at the new rate, to determine to the nearest dollar, how much did he save due to the devaluation the following calculation must be performed:
(9,900 / 4.5) - (9,900 / 6.5) = X
2,200 - 1,523.07 = X
676.92 = X
So, rounded to the nearest dollar, Bob saved $ 677 by buying the carpet on Wednesday.
This is done by factoring. 1/8 is smaller than 1/2, so we can factor a 1/8 out of 1/2. This is what that looks like:

, because factoring after all is a form of division. When we divide a fraction by a fraction, we bring the lower fraction up and flip it to multiply, giving us this:

. This of course reduces to 4. So when we factor out 1/8, what we will have then is

, choice D from above.

The volume formula of a pyramid is:
V =

x length x width x height
The given are
Length = 24 cm, Width = 18 cm, Height = 35 cm
Substitute the values to find the volume
V =

x 24 x 18 x 35
V = 5040 cm³
