Answer:
Necesitamos agregar 40 libras del café La Finca
Step-by-step explanation:
Sea x el número de libras de café de La Finca a mezclar.
Entonces, la cantidad total de libras que obtendremos en la mezcla será (x + 80) libras.
Ahora trabajemos con los precios; Tenemos x libras de La Finca a $ 5 por libra, con 80 libras de café a $ 2 por libra para dar una mezcla de (x + 80) a $ 3 Así, sumaremos el precio de La Finca más la otra variante para llegar al costo de la nueva mezcla.
Matemáticamente;
5 (x) + 2 (80) = 3 (x + 80)
5x + 160 = 3x + 240
5x -3x = 240-160
2x = 80
x = 80/2 x = 40
Answer:
Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)
Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
Step-by-step explanation:
$4.09 has been changed to $3.59.
Percent change = [(Value after - Value before) / Value before]*100

% ( Rounded to nearest tenth)
Percentage decrease is 0.1% ( Rounded to nearest tenth)
Now lets calculate the percentage change from $3.59 to $4.09.
Percent change = [(Value after - Value before) / Value before]*100
=

Percentage increase is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
Step-by-step explanation:
multiply the first equation by 1, the second by -1 and add.
x + 2y = -16
-x - 6y = 28
--------------------
0 - 4y = 12
-4y = 12
y = -3
x + 2×-3 = -16
x - 6 = -16
x = -10
