Se vendieron un total de 430 boletos para la obra de teatro escolar. Los boletos eran o de adulto o de estudiante. Se vendieron
BartSMP [9]

Resolviendo un sistema de ecuaciones, veremos que se vendieron 250 boletos de adulto.

<h3>¿Cuántos boletos de adulto fueron vendidos?</h3>

Definamos las variables:

  • x = boletos de adulto vendidos.
  • y = boletos de estudiantes vendidos.

Se vendieron un total de 430 boletos, entonces:

x + y = 430

Y se vendieron 70 boletos de estudiante menos que boletos de adulto:

y = x - 70

Tenemos el sistema de ecuaciones:

x + y = 430

y = x - 70

Para resolverlo, podemos reemplazar la segunda ecuación en la primera:

x + y = 430

x + (x - 70) = 430

2x = 430 + 70 = 500

x = 500/2 = 250

Se vendieron 250 boletos de adulto.

This is a geometric sequence with a common ratio of 2

an = a1 * r^(n - 1)
n = term to find = 21
a1 = first term = 0.05
r = common ratio = 2
now we sub
a21 = 0.05 * 2^(21 - 1)
a21 = 0.05 * 2^20
a21 = 0.05 * 1048576
a21 = 52428.80 <==== after working 21 days

koban [17]

Answer: $5.1

Step-by-step explanation:

From the question, we are informed that thee price of the skateboard is $85 and that the sales tax is 6%.

To calculate the sales tax for the skateboard in dollars in cents, we find 6% of$85. This will be:

= 6% of $85

= 6% × $85

= 6/100 × $85

= 0.06 × $85

= $5.1

= 5 dollar, 10 cents

E is really just 10, and +7 means it's a positive exponent. So it is 3.82 x 10 to the power of 17. I can't write exponents on my phone, but this is scientific notation.
