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.

If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5
Remark
2015 is an odd numbered year. It is not a leap year. It has 365 days in it.
Equation
Total deaths = deaths / day * number of days
Givens
Total deaths = 32800
deaths / day = ???
number of days = 365
Sub and solve
32800 = x * 365 Divide by sides by 365
32800 / 365 = x
x = 89.86 deaths per day.
Problem
Do you round up, down or leave the number as it is?
I would round up 90 deaths per day.
Discussion
Just how much are you out?
Total deaths in a year (rounded) = 90 * 365
Total deaths in a year (rounded)= 32850 which is 50 too many
Suppose you round down
Total death/day = 89 * 365 = 39485 Rounding up is going to be better if you round at all.
Perhaps you should not round the answer at all and leave it at
89.86 <<<<< answer.
If you have choices, please list them.
