Answer:

La respuesta correcta es la opción d) 5 a 1.

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 (I_{2019}) con respecto a sus ingresos en 2018 (I_{2018}), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

I_{2019} = 20\% \: I_{2018}      

I_{2019} = \frac{20}{100}I_{2018}      

\frac{100}{20}I_{2019} = I_{2018}        

5I_{2019} = I_{2018}                  

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

Espero que te sea de utilidad!
