$59.99 if it where on sake for 25% off
gulaghasi [49]
The item would cost approximately $45. You can do this by taking the price of the item ($60) and multiply by the percent (25%). 60 x 0.25 = 15. That is the discount you would subtract from the item itself. Now you would take the original price ($60) and subtract the discount ($15). 60 - 15 = 45.

Answer:

La Provincia del Guayas comprime el 25.1% de la población de Ecuador. A su vez, la Ciudad de Guayaquil tiene una población igual al 15.58% de la población ecuatoriana.

Step-by-step explanation:

Dado que vivo en la Provincia del Guayas, y en la ciudad de Guayaquil, los datos de población solicitados son los siguientes:

-Provincia del Guayas: 4.387.434 habitantes, es decir, un 25.1% del total de la población de Ecuador, que es de 17.475.570 habitantes, conforme surge del siguiente calculo:

17.475.570 = 100

4.387.434 = X

4.387.434 x 100 / 17.475.570 = X

438.743.400 / 17.475.570 = X

25,10 = X

-Ciudad de Guayaquil: 2.723.665 habitantes, es decir, un 15.58% del total de la población de Ecuador, conforme surge del siguiente cálculo:

17.475.570 = 100

2.723.665 = X

2.723.665 x 100 / 17.475.570 = X

272.366.500 / 17.475.570 = X

15.58 = X
