se vendieron 144 boletos. 2 pesos por adulto y un peso por niño, si se gastaron 207 pesos cuantos boletos de adulto se vendieron
natulia [17]

Answer:

Se vendieron 81 boletos de niños y 63 boletos de adultos.

Step-by-step explanation:

La cantidad de boletos vendidos es igual a:

144 = a + n   (1)

En donde <em>a </em>es por adultos y <em>n</em> por niños

A su vez, el dinero gastado equivale:

207 = 2*a + 1*n   (2)

Resolviendo la ecuación (1) para <em>a:</em>

a = 144 - n   (3)

Introduciendo (3) en la ecuación (2) tenemos:

207 = 2*(144 - n) + n

n = 81

Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):

a = 144 - n = 144 - 81 = 63

Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.  

Espero que te sea de utilidad!

A town has a population of 6000 and grows at 3.5% every year. To the nearest year, how long will it be until the population will
kotykmax [81]

Answer:

5 years.

Step-by-step explanation:

Every year the population increases by a factor 103.5% or  1.035.

The equation relating population and time in years is:

P = 6000(1.035)^t  (This is an example of  exponential growth)

So we have:

7100 = 6000(1.035)^t

(1.035)^t = 7100/6000

(1.035)^t = 1.1833

t ln 1.035 = ln 1.1833

t = ln 1.1833/ln 1.035

= 4.89.
