We assume, that the number 50 is 100% - because it's the output value of the task. 
<span>We assume, that x is the value we are looking for. 
</span>If 100% equals 50, so we can write it down as 100%=50. 
<span>We know, that x% equals 20 of the output value, so we can write it down as x%=20. 
</span>Now we have two simple equations:
1) 100%=50
2) x%=20
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=50/20
Now we just have to solve the simple equation, and we will get the solution we are looking for.

100%/x%=50/20
<span>(100/x)*x=(50/20)*x </span>
<span>100=2.5*x      </span>
<span>100/2.5=x </span>
<span>40=x </span>
<span>x=40</span>

Farmer Kipp sold 25 horses for a total of $7500 in January and 25 horses for a total of $10500 in February. What is the average
insens350 [35]

Answer:

So Average Price of horse is $360

Step-by-step explanation:

Given:

25 horses sold in January for $ 2500

25 horses sold in February for $10500

TO find:

Average price of horse = ?

Solution:

Average price is usually found out by adding all the values and dividing by its total no of values

Now in our case

Total Horse = 25 + 25

                     = 50

Total Money = $7500 + $10500

                      = $18000

Average Price =\frac{total price}{total horses}

Average Price =\frac{18000}{50}

                                =$360

So Average Price of horse is $360

Please help me I really need this and show your work if possible
kogti [31]
The temperature at 9 am was -11 degrees.

We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have:
-10 - 2 = -12 (6 am - 7 am)
-12 - 5 = -17 (7 am - 8 am)
-17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)

And our final answer is -11 degrees Fahrenheit.

How might foreign investment be problematic for a transitioning economy?
KengaRu [80]
The foreign investment is problematic for the economy of a transitioning country because it provides profit to the foreign investors only. They use cheap labor of the developing country. Moreover, the local producers and investors are directly harmed. The major profits are going in the pockets of the other nation's investors. This also causes inflation in the country.
