a book store cost $80 a day to keep open, and it spends $15 for each book that it sells. if each book sells for $23, what is the
aalyn [17]

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>

BEP = \frac{\text{Fixed cost}}{\text{Selling price - variable cost}}

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,

BEP = \frac{80}{23-15}\\\\BEP = \frac{80}{8}\\\\BEP = 10

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

The sides of two cubes are in the ratio 2:1. What is the ratio of their volumes ?
olasank [31]

Please mark as brainliest

Answer:

we know that, Volume of cube=a³

Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)

Step-by-step explanation:

ATQ: 2x=a³ and, x=A³

a=³√2x and, A=x

we know that, surface area of cube is 6a²

Thus, surface area of 1st cube = 6(³√2x)²

= 6³√4x²

Surface area of 2nd cube=6(x)²=6x²

Ratio of S.A=(6³√4x²)÷(6x²)

Ratio of S.A=³√4:1

Have a great day, be safe and healthy
