La matemática financiera experimentó grandes avances con la creación de la banca y los negocios creados por los emprendedores. E

ste tipo de matemática se puede encontrar en las transacciones que realizan los concesionarios de carros, como en el siguiente caso: el costo anual (C de operación) de un automóvil nuevo es C= f + cm; f es el costo fijo (depreciación, seguros, impuestos), c es el costo de operación por kilómetro y m es el número de kilómetros recorridos. El costo total por 15000 Km es de 3000 USD, y el costo por 20000 Km es 3500 USD. Encuentra el costo fijo y el costo por kilómetro.

Answer:

c = \frac{1}{10}

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

C = f+cm

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

3000=f+c15000, 3500=f+c20000

Si restamos la segunda ecuación de la primera, tenemos que

3500-3000 = f-f+(20000c-15000c)

Luego

500 = 5000c

Entonces c = \frac{500}{5000} = \frac{1}{10}

Si tomamos la primera ecuación, tenemos que 3000-\frac{15000}{10} = f. Es decir,

3000-1500 = f = 1500

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.

In-s [12.5K]

Answer: 32 buttons

Step-by-step explanation:

Matt has 11 white buttons.

Matt has 9 fewer brown buttons than white buttons. This means he has (11 -9) = 2 brown buttons

Matt has 17 more grey buttons than brown buttons. This means that he has (2 + 17) = 19 grey buttons.

The total number of buttons that Matt has will be;

= 11 white + 2 brown + 19 grey

= 32 buttons

What operation would you we to convert cups to gallon explain
UkoKoshka [18]
We'd divide. 

This is because:

Gallons are much more than cups. If we cant to convert cups to gallons, we divide to get a smaller unit. 

Example: There are 32 cups on the table. How many gallons are there?

32/amount of cups per gallon
