First you need to get the unit rate by dividing 715 by 13, getting 55 miles per hour. You then will need to divide 495 by 55 to get the answer of 9

The break even point for this book store is 10
<em><u>Solution:</u></em>
Given that, book store cost $80 a day to keep open, and it spends $15 for each book that it sells
Cost to open the book store = $ 80
<em><u>The formula for solving the break even point (BEP) is:</u></em>
Fixed Cost is the cost that remains constant whether the services provided or products sold increases or decreases
Variable Cost is the cost that varies or differs in proportion to the products or services produced, whether they increased or decreased
In this problem,
Fixed cost = $ 80
Selling price = $ 23
Variable cost = $ 15
Therefore,
Thus break even point for this book store is 10
In order for the bookstore to continue its business, it should sell at least 10 books to meet its $80 cost
19 and 42 are coprime, so we can use the CRT right away. Start with
Taken mod 42, we're left with a remainder of 19. Notice that
so we need to multiply the first term by 3 to get the remainder we want.
Next, taken mod 19, we're left with a remainder of 4. Notice that
so we need to multiply the second term by 6.
Then by the CRT, we have
so that any solution of the form is a solution to this system.
