Mathematics

BigorU [14]3 years ago
8 0

Respuesta: 70 pesos

Explicación paso a paso:

Dado que:

Sea la cantidad total poseída = t

Fracción gastada en alimentos = 1/3 t = t / 3

Fracción gastada en pasaje = 1/8 t = t / 8

Monto restante después del gasto total = 39 pesos

Fracción total gastada:

(t / 3 + t / 8)

= (8t + 3t) / 24

= 11t / 24

Fracción restante después del gasto total:

(t - 11t / 24)

= 13t / 24

Por lo tanto,

Fracción restante después del gasto total = Cantidad restante después del gasto total

13t / 24 = 39

13t = 936

t = 936/13

t = 72 pesos

Por lo tanto,

Monto total poseído = 72 pesos

given that x is the number of years between 1980-2000

the number of years is 20years

put x= 20 in the expression for the cost we have
