Usando proporciones y regla de três, tiene-se que cada pizza le costó $58.33.

Para encontrar el precio de cada pizza, usa-se proporciones, aplicando una regla de três.
A medida que aumenta la cantidad, también lo hace el precio, por lo que las medidas son directamente proporcionales y se aplica la multiplicación cruzada.
$350 por 6 pizzas. ¿cuánto por 1?

La regla de três es:

$350 - 6 pizzas

x - 1 pizzas

Aplicando multiplicación cruzada:

$6x = 350$

$x = \frac{350}{6}$

$x = 58.33$

There are 162 magazines and books in a library. There are 54 more books

Strike441 [17]

Answer:

108 books.

Step-by-step explanation:

Let the number of magazines = m

Let the number of books = b

Given the following data;

Total number of m & b = 162

Translating the word problem into an algebraic equation, we have;

$b = m + 54$ ......equation 1

$m + b = 162$ ......equation 2

Substituting equation "1" into equation "2" we have;

$m + m + 54 = 162$

$2m + 54 = 162$

$2m = 162 - 54$

$2m = 108$

$m = \frac {108}{2}$

m = 54

Now to find the number of books;

$b = m + 54$

Substituting the value of "m" into the equation, we have;

$b = 54 + 54$

b = 108

Therefore, the total number of books in the library is 108 books.
