The number of books sold is 473.
<u>Step-by-step explanation:</u>
- The original cost of each book = $0.64
- The selling price of each book = $0.75
The difference between the original price and selling price of the book gives the profit per book.
The profit of one book = Selling price - Original price
Let,
- The total number of books be 'x'.
- The number of books sold be 'y'.
- The unsold books is 100.
- The total profit is -12 because it was gone to a loss of $12.
Therefore, the equation is formed as
total Profit = 0.75y - 0.64x
⇒ 0.75y - 0.64x = -12 --------(1)
Total books = sold books + unsold books
x = y + 100
⇒ x-y = 100 -------(2)
Substitute x= 100+y in the eq(1),
0.75y - 0.64(100+y) = -12
0.75y - 64 -0.64y = -12
0.11y = -12 +64
y = 52 / 0.11
y = 472.7
y ≅ 473
The number of book sold is 473 books.
The total number of books is (100+473) = 573 books.

Fraction form: x = ln(5)/ln(10)
Decimal form: 0.69897000

The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be

Answer:
a) The profit will be: 
b) Since the profit is -9500 (negative) so, company will not gain any profit if they produce 300 bicycles.
Step-by-step explanation:
Cost of Bicycles= 
Revenue generated = 
Find a polynomial that represent profits
The formula used for finding profit is:

So, the profit will be: 
If the company can produce bicycles y= 300
The profit will be:

Since the profit is -9500 (negative) so, company will not gain any profit if they produce 300 bicycles.
