Answer:

We need to add 7 pounds of $9.5 premium coffee to make a blend of coffee that $10.

Step-by-step explanation:

Lets take the amount of $9.50 coffee added was x pounds.

The requirement is that the value of 1 pound of resulting mixture of coffee to be $10.

We can use the weighted average value to find the value of the resulting mixture.

⇒\frac{(9.5*x)+(11.75*2)}{(x+2)} =10

=(9.5*x)+(23.5)=10(x+2)

=9.5x+23.5=10x+20

=3.5=0.5x

=x=7

So we need to add 7 pounds of $9.5 premium coffee to make a blend of coffee that $10.

I need some help please
gizmo_the_mogwai [7]

Answer:

a) -10

b) 7

Step-by-step explanation:

a) 2(x + 3) = x - 4

=  > 2x + 6 = x - 4

=  > 2x - x =  - 4 - 6

=  > x =  - 10

b) 4(5x - 2) = 2(9x + 3)

=  > 20x -8 = 18x + 6

=  > 20x - 18x = 8 + 6

=  > 2x = 14

=  > x =  \frac{14}{2}  = 7
