Answer:
y = 40x + 35
Step-by-step explanation:
Let x represent each month of service in the equation
Since it is $40 for each month, the price for each month can be represented by 40x.
The $35 fee will represent the y intercept, and will be added to 40x in the equation.
Put this together in the equation y = mx + b
y = 40x + 35
So, the linear equation to model the situation is y = 40x + 35
-1(18+4x)=8
Then you distribute
-18-4x=8
-4x=26
X= -6.5
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.

6 blocks :) I won’t explain it tho lol
315/356 = about 0.88 or 88%. <span>
64/144= about .044 or 44%
</span><span>They will not have equal opportunity to get the math class they requested, if both percents were equal, it would be fair. For honors students, 88% of them will get the class they requested, but for non honors students it's 44%.</span>
