Answer:

Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

Step-by-step explanation:

De acuerdo con el enunciado, x es la cantidad mínima de artículos a un precio de p. Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:

x \cdot p = 1200 (1)

p = 50-0.5\cdot x (2)

Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:

x\cdot (50-0.5\cdot x) = 1200

50\cdot x -0.5\cdot x^{2} = 1200

0.5\cdot x^{2}-50\cdot x +1200 = 0 (3)

Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:

x_{1} = 60, x_{2} = 40

De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

Determine the time necessary for P dollars to double when it is invested at interest rate r compounded annually, monthly, daily,
kipiarov [429]

Answer:

  • annually: 9.01 years
  • monthly: 8.69 years
  • daily: 8.67 years
  • continuously: 8.66 years

Step-by-step explanation:

For interest compounded in discrete intervals, the formula is ...

  A = P(1 +r/n)^(nt)

We want to find t for P=1 and A=2, so we have ...

  2 = (1 +r/n)^(nt)

  ln(2) = nt·ln(1+r/n)

  t = ln(2)/(n·ln(1+r/n))

A table of values for r=0.08 is attached.

__

For continuous compounding, the formula is ...

  A = Pe^(rt)

  t = ln(A/P)/r = ln(2)/0.08 ≈ 8.66434 . . . . years

__

  • annually: 9.01 years
  • monthly: 8.69 years
  • daily: 8.67 years
  • continuously: 8.66 years

Erica had 6 coins in her coin collection. she goes to a coin show and buys some coins. how many dose she have now?
Anuta_ua [19.1K]

Since, it is not given how many coins did Erica buy at the coin show, so, we can suppose that Erica bought "n" coins from the coin show.

Now, we know that Erica already had 6 coins in her coin collection before she went to the coin show and bought the "n" coins.

Therefore, the total number of coins that Erica will have in her possession after buying "n" coins from the coin show will be 6+n.
