It would include 25 gifts for the cost the same amount either way
<em><u>Solution:</u></em>
Let "a" be the number of gifts to be wrapped
He can get them wrapped at the department store, which charges $2 per gift
Therefore,
Cost at department store: 2(number of gifts)
Cost at department store: 2a
The customer can pay his niece a flat fee of $50 to wrap all of his gifts
Cost at his niece: 50
He has a certain number of small packages, it would cost the same amount either way
Therefore,
Cost at department store = Cost at his niece
2a = 50
Divide both sides by 2
a = 25
Thus it would include 25 gifts for the cost the same amount either way

Answer:
![12\ ft](https://tex.z-dn.net/?f=12%5C%20ft)
Step-by-step explanation:
The question in English is
A 13-foot long staircase rests on a wall, so that the base of the staircase is separated from the wall, at floor level, at a distance of 5 feet. Calculate the height of the ladder on the wall. Remember that in a right triangle, the hypotenuse, squared, is equal to the sum of the squares on the other sides. If necessary, approach the tenth foot
Applying the Pythagoras Theorem
![13^{2} =5^{2}+h^{2}](https://tex.z-dn.net/?f=13%5E%7B2%7D%20%3D5%5E%7B2%7D%2Bh%5E%7B2%7D)
Solve for h
![h^{2}=13^{2}-5^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D13%5E%7B2%7D-5%5E%7B2%7D)
![h^{2}=144](https://tex.z-dn.net/?f=h%5E%7B2%7D%3D144)
![h=12\ ft](https://tex.z-dn.net/?f=h%3D12%5C%20ft)
