Answer:
Step-by-step explanation:
p + c = 110
p = c + 100
c + 100 + c = 110
2c + 100 = 110
2c = 110 - 100
2c = 10
c = 10/2
c = 5 .......cost of the phone case
p = c + 100
p = 5 + 100
p = 105 <=== cost of the phone
Given that Nicholas has a 115 fantasy and science fiction books which is 46% of his collection.
Now we have to find what is total number of books in his collection.
Let number of books in Nicholas collection = x
then number of fantasy and science fiction books = 46% of x = 0.46x
We already know that he has 115 fantasy and science fiction books, so both values will be equal and give equation:
0.46x=115
now we can solve this equation to find the answer.
![x=\frac{115}{0.46}](https://tex.z-dn.net/?f=%20x%3D%5Cfrac%7B115%7D%7B0.46%7D%20)
x= 250
Hence final answer is:
Nicholas has 250 books in his collection.
