Question
For the annual school fundraisers, Santos has p pledges each for c centavos per lap that he jogs. If his school track has 4 laps per mile and Santos raises a total of d pesos, how many miles did he jog in terms of p, c and d?
Solution
Para resolver esta pregunta, primero necesitamos entender cómo se relacionan las variables.
-
Cada vez que Santos corre una vuelta, recibe p promesas de c centavos. Por lo tanto, cada vuelta que corre, recauda p*c centavos.
-
Como hay 4 vueltas en una milla, cada milla que corre, recauda 4pc centavos.
-
Pero la cantidad total que recauda, d, está en pesos. Necesitamos convertir los centavos a pesos. Como hay 100 centavos en un peso, cada milla que corre, recauda 4pc/100 pesos.
-
Entonces, si recauda un total de d pesos, el número de millas que corre es d / (4pc/100).
Por lo tanto, el número de millas que Santos corre es d / (4pc/100).
