El saco tiene un precio original de 400 soles.
<h3>¿Cómo determinar el precio inicial de un saco comprado con descuento?</h3>
En este problema tenemos el caso de un precio de compra (P'), en soles, que es resultado de aplicar dos descuentos consecutivos al precio original del saco (P), en soles. El precio es el resultado de multiplicar el precio original por los dos factores de porcentaje, descrito por la siguiente fórmula:
P' = P · (1 - r₁ / 100) · (1 - r₂ / 100), 0 ≤ r₁, r₂ ≤ 100.
Donde:
- r₁ - Porcentaje del primer descuento.
- r₂ - Porcentaje del segundo descuento.
Si sabemos que P' = 224, r₁ = 30 y r₂ = 20, entonces el precio original del saco es:
224 = (1 - 30 / 100) · (1 - 20 / 100) · P
224 = 0.7 · 0.8 · P
P = 224 /(0.7 · 0.8)
P = 400
El precio original del saco es de 400 soles.

Answer:
Step-by-step explanation:
Jill makes purses and backpacks.
Let x represent the number of foot of fabric required to make a purse.
Let y represent the number of foot of fabric required to make a backpack.
To make each purse,she uses 1 foot less than half the amount of fabric she uses to make a backpack. This means that
x = (y/2) - 1
Therefore, the amount of fabric that Jill needs to make backpack will be
y/2 = x-1
y = 2(x-1) = 2x - 2
The number of feet of fabric that she will use to make a purse is
x = (y/2) - 1
1/10 for Hugh to be first and after he is picked only 9 students remain so 1/9 for stu and after he is picked only 8 remain to be chosen so 1/8 for lou. The chance of all three happening is 1/10×1/9×1/8=1/720 this is the probability that 3 triplets will be chosen in that exact order out of 10 students
