L Por el alquiler de un coche cobran 100

Mathematics
1 answer:
Katen [24]3 years ago
3 0

Answer:

Sabemos que el costo del alquiler es 100 pesos diarios, más 0.30 pesos por kilómetro.

Entonces, solo por alquilar el coche por un día, hay que pagar 100 pesos.

Si además lo conduces x kilómetros, tendrás que pagar x veces 0.30 pesos.

Entonces el costo diario, en pesos, será:

C(x) = 100 + 0.30*x

Para graficar esta ecuación simplemente se deben encontrar dos pares:

(x, C(x)) en un eje de coordenadas, y luego conectarlos con una línea.

Por ejemplo, si tomamos:

x = 0

C(0) = 100 + 0.30*0 = 100

entonces tenemos el par (0, 100)

si x = 10

c(10) = 100 + 0.30*10 = 100 + 3 = 103

entonces tenemos el par (10, 103)

Ahora podemos graficar esos dos puntos y conectarlos con una línea, como en el ejemplo de abajo.

b)  

También queremos conocer el costo diario si se han hecho un total de 300km.

Entonces simplemente reemplazamos x por 300 en la ecuación del costo:

C(300) = 100 + 0.30*300 = 100 + 90 = 190

El costo será de 190 pesos.

Ronch [10]

<u>Part a)</u> Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime

Let

E-------> the amount of money earned

x------> number of hours worked

we know that

For x\leq35

E=14x

therefore

<u>the answer part a) is</u>

E=14x

<u>Part b) </u>Create an equation that shows the amount of wages earned, T, for working y hours of overtime

Let

T-------> the amount of money earned

y------> number of hours of overtime

we know that

T=14*35+20y

T=\$490+20y

therefore

<u>the answer part b) is</u>

T=\$490+20y

<u>Part c)</u> Allison earned $610 in 1 week. How many hours (regular plus overtime) did she work?

we know that

35\ hours=\$490

\$610-\$490=\$120

Divide \$120 by  \$20----> to obtain the hours of overtime

\frac{120}{20}=6\ hours\ of\ overtime

So

Allison works

35+6=41\ hours

Regular=35\ hours\\ Overtime=6\ hours

therefore

<u>the answer part c) is</u>

Regular=35\ hours\\ Overtime=6\ hours
