Let x =Alice’s original amount of money,
y = Bob’s original amount of money
And n = the dollars they are referring to
So, the equation are:
If Alice receives dollars from Bob, then she will have 3
times as much money as Bob,
x + n = 3(y - n)
x +n = 3y – 3n
x = 3y-3n-n
x = 3y – 4n
And if Alice give dollars to Bob, the she will have 2 times
as much money as Bob,
x – n = 2 (y +n)
x – n = 2y + 2n
x = 2y + 2n + n
x = 2y + 3n
As, x = x
So, 3y – 4n = 2y + 3n
3y = 2y + 3n + 4n
3y – 2y = 3n + 4n
Y = 7n
Find x in terms of n also,
x = 2y + 3n, replace y with 7n
x = 2(7n) + 3n = 14n + 3n
x = 17n
If neither gives the other any money, the ratio of the amount
of money Alice has to the amount Bob has = x/y
Replace x and y with their values, x = 17n and y = 7n
= 17n / 7n
The ratio is 17:7
Here are the answers that would best complete the given paragraph above.
The salesperson says, "For the money, you will find no better water reclamation system anywhere!" The customer thinks the salesperson has just told himthat his product is cheaply made and only fairly successful at cleaning the water so it can be reused.

<h3>What is the Exchange rate?</h3>
- The rate at which one currency will be exchanged for another is known as the exchange rate in the world of finance.
- Most often, currencies are national ones, but they can also be supra-national ones like the euro or sub-national ones like Hong Kong.
- The value of one country's currency in respect to another currency is also thought of as the exchange rate.
- An interbank exchange rate of 114 Japanese yen to the US dollar, for instance, indicates that 114 will be converted into $1 or that $1 will be converted into 114. In this instance, it is said that the cost of a dollar in terms of the yen is 114, or, translated into dollars, that the cost of a yen in terms of the yen is $1/114.
<h3>What is an export?</h3>
- When it comes to international trade, export is a good made in one nation and sold in another, or a service rendered in one nation to a national or resident of another nation.
