Step-by-step explanation:
Dada la siguiente información:
Costo total= $1,956
<u>Para calculate el valor parcial, debemos usar la siguiente información:</u>
Precio proporcional= costo total* ( 1 - porcentaje de descuento)
50%:
Precio proporcional= 1,956*(1 - 0.5)
Precio proporcional= $978
25%:
Precio proporcional= 1,956*(1 - 0.75)
Precio proporcional= $489
Let's call the bigger number n
So the smaller number is 2/5n
So n + 2/5n = 21
Which is equivalent of n + 2n/5 = 21
Then you need to get rid of the fraction by multiplying everything by 5
5n + 2n = 105
Or simply
7n = 105
Divide both sides by 7 to isolate n
n = 15
So the larger number is 15
Now we need to work out 2/5 of 15 to work out the smaller number
(15/5 [the denominator])*2 [the numerator] = 6
So the two numbers are 15 and 6
J/4 - 8 < 2
J/4 < 2 + 8
J/4 < 10 ...multiply both sides by 4
J < 10 * 4
J < 40
