On Tuesday, Bob brought home an oriental carpet on approval. The price in the store was 9900 Turkish Lira, but Bob was going to pay in dollars. On Tuesday, one dollar was worth 4.5 Turkish Lira. On Wednesday, the Turkish Lira was devalued such that one dollar was now worth 6.5 Turkish Lira. Feeling lucky by this change, Bob then bought the rug on Wednesday, paying the price of 9900 Turkish Lira with dollars at the new rate. To the nearest dollar, how much did he save due to the devaluation?
Answers
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.

which of the following is the solution to the equation 25(z-2 )= 125?
A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5
Answers
Answer:
The answer is z = 7.
Step-by-step explanation:
1) Divide both sides by 25.
[tex]z - 2 = \frac{125}{25} [/tex]
2) Simplify 125/25 to 5.
[tex]z - 2 = 5[/tex]
3) Add 2 to both sides.
[tex]z = 5 + 2[/tex]
4) Simplify 5 + 2 to 7.
[tex]z = 7[/tex]
Thus, the answer is z = 7.

Suppose that appoximately 261,000,000 people live in the united states. Of these people 37,600,000 speak a language other than english at home who speak another lanague at home over 45 percent speak spanish
Answers
Answer:
16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.
Step-by-step explanation:
Given that approximately 261,000,000 people live in the United States, and of these people 37,600,000 speak a language other than English at home, of which over 45 percent speak Spanish, to determine the number of people who speak Spanish in the United States, the following calculation has to be done:
37,600,000 x 0.45 = X
16,920,000 = X
261,000,000 = 100
16,920,000 = X
16,920,000 x 100 / 261,000,000 = X
6.48 = X
Thus, some 16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.

Answer: 43.75 drawers
Step-by-step explanation:
Equation: 10 - 7.5 = 2.5 and when you subtract 2.5 until the Number of Drawers (x) is 0, then you get 0 for Total Volume (y), so y =2.5x+0 or y = 2.5x
Answer: Substitute 17.5 into x.
y = 2.5(17.5)
y = 43.75 drawers
