Sea:

\n

\n

\\begin{align}
\\simplify[std]{x+{c}}&: \\text{La cantidad mayor de dinero.}\\\\\\\\\\simplify[std]{x}&: \\text{La cantidad menor de dinero.}
\\end{align}

\n

Del enunciado podemos plantear la siguiente ecuación:

\n

\\begin{align}
\\simplify[std]{(x+{c})/x}=\\simplify[std]{{a/b}}
\\end{align}

\n

Ahora resolvemos la ecuación:

\n

\\begin{align}
\\simplify[std]{{b}(x+{c})}=\\simplify[std]{x*{a}}\\\\\\\\\\simplify{{b}*x+{c*b}}=\\simplify{x*{a}}\\\\\\\\\\simplify{x}=\\simplify{{(c*b)/(a-b)}}
\\end{align}

\n

La cantidad mayor de dinero es de: $\\,\\$$ $\\simplify{{c+(c*b)/(a-b)}}$

\n

La cantidad menor de dinero es de: $\\,\\$$ $\\simplify{{(c*b)/(a-b)}}$
