El precio de un ordenador portátil ha aumentado un 25% y posteriormente fue rebajado un cierto porcentaje.Calcule que porcentaje

ZanzabumX [31]

Answer:

Se requiere un 20 por ciento de descuento.

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in the same language)

Sea $p_{o}$ el precio original del computador portatil, el nuevo precio es:

$p_{1} =\left(\frac{100\,\% + 25\,\%}{100\,\%} \right)\cdot p_{o}$

$p_{1} = 1.25\cdot p_{o}$

Si $p_{2} = p_{o}$ , entonces el porcentaje requerido para recuperar el precio original es:

$r = \left(1-\frac{p_{2}}{p_{1}} \right)\times 100\,\%$

$r = \left(1-\frac{p_{o}}{1.25\cdot p_{o}} \right)\times 100\,\%$

$r = \left(1-\frac{1}{1.25} \right)\times 100\,\%$

$r = 20\,\%$

Se requiere un 20 por ciento de descuento.

If f(x)=x^2 and g(x)=1÷2x+3 find g(f(-1))

gogolik [260]

ANSWER

$g(f( - 1)) = \frac{1}{5 }$

EXPLANATION

The given function is:

$f(x) = {x}^{2}$

and

$g(x) = \frac{1}{2x + 3}$

$g(f(x)) = g( {x}^{2} )$

$g(f(x)) = \frac{1}{2{x}^{2} + 3 }$

To find g(f(-1)), we substitute x=-1, to obtain;

$g(f( - 1)) = \frac{1}{2{( - 1)}^{2} + 3 }$

We simplify the square in the denominator to get,

$g(f( - 1)) = \frac{1}{2+ 3 }$

We now add the denominator to obtain;

$g(f( - 1)) = \frac{1}{5 }$

The selling price s , of an item is S equals C plus MC where C is the cost of the item and Emma is the percent markup based on c

Evgen [1.6K]

9514 1404 393

Answer:

M = (S -C)/C

Step-by-step explanation:

Starting with ...

S = C + MC

we want to solve for M.

S - C = MC . . . . subtract the term not containing M

(S -C)/C = M . . . . divide by the coefficient of M

Solved for M, the formula is ...

M = (S -C)/C
