Un grupo de 25 estudiantes aportará $4.00 cada uno, para comprar una pizarra.
Svetlanka [38]

Usando algebra, veremos que cada estudiante debe aportar $5.00.

<h3>¿Cuál será el aporte de cada estudiante?</h3>

En el caso en el que hay 25 estudiantes, cada uno aporta $4.00, entonces la cantidad total que se colecta es:

25*$4.00 = $100

Ahora, en el caso de que hay 20 estudiantes, cada uno aportara una cantidad x, de tal forma que:

20*x = $100

Debemos resolver la ecuación de arriba para x:

x = $100/20 = $5.00

Es decir cada estudiante debe aportar $5.00

What percent of the current number of states had joined<br> the United States by the year 1863?
sukhopar [10]

we know the 100% is 50 today, by 1863 there were 35, so what is 35 in percentage off 50?

\begin{array}{ccll} amount&\%\\ \cline{1-2} 50&100\\ 35&x \end{array}\implies \cfrac{50}{35}=\cfrac{100}{x}\implies \cfrac{10}{7}=\cfrac{100}{x} \\\\\\ 10x=700\implies x=\cfrac{700}{10}\implies x=70
