Cuantos yenes se pueden comprar con 200 pesos mx ? si los yenes cuestan 0.178 centavos ayuda rapido
Sergeeva-Olga [200]

Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.

<h3>¿Qué es una proporción?</h3>

Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.

En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.

Por eso, la <em>regla de tres</em> es:

1 yene - 3100 pesos

x yenes - 200 pesos

Aplicando multiplicación cruzada:

3100x = 200

x = \frac{200}{3100}

x = 0.0645

Con 200 pesos mx se pueden comprar 0.0645 yenes.

A video store rents new movies for $5 and older movies for $4. The owner wants
AnnyKZ [126]

Answer:

2480 new movies

Step-by-step explanation:

1) First you need to find out how much money the 400 older movies made.

400*4=1600

2) Next subtract that amount from the amount of revenue that the wants.

14000-1600=12400

3) Divide the amount of leftover money by the amount that a new movie costs to rent

12400/5=2480

This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.
