Responder:

$ 131.25

Explicación paso a paso:

Dado que :

Importe pagado tras sucesivos descuentos del 10% y 20%

Sea el costo original = x

Importe final tras ambos descuentos = 94,5

Primer descuento = (1 - 0.1) x = 0.9x

Segundo descuento: (1 - 0.2) de 0.9x = 0.8 de 0.9x = 94.5

Es decir ; 0,8 * 0,9x = 94,50

0,72x = 94,50

Dividir ambos lados por 0,72

0,72x / 0,72 = 94,50 / 0,72

x = 131,25

Por lo tanto, precio original = $ 131.25

I am weighed on scales which have a 10% error, that is, the scales show me 10% heavier than my real weight. If I actually weigh
stiks02 [169]
Remember you said the scale shows you 10% heavier.

So that's an increase of 10%

So value = 10% + 100% = 110%

So scale would show  110% of 82

110% of 82

= (110/100)  * 82

= 1.1 * 82

= 90.2

OR

We can simply find 10% of 82 and add it to the original 82.

10% of 82

(10/100) * 82

0.1 * 82 = 8.2

8.2 + 82 = 90.2    Same answer as before.

So scale shows 90.2 kg.
