X pounds of $3
y pounds of $3.25
x+y = 200
300x + 325y = 320*200
300x + 325y = 64000
x+y =200
300x +325y =64000
Solve by eliminating
Multiply top one w/-300
-300y =60000
325y=64000
25y = 4000
y= 160 then
x + 160= 200
x = 40
So the mixture has;
40 pounds of $3 coffee
160 pounds of $3.25 coffee

Answer:
x=16;y=8
Step-by-step explanation:
x=length
y=width
the length of a rectangle is twice the width
so,
x=2y........(1)
the perimeter is 48 inches
so,
2(x+y)=48
x+y=24....(2)
2y+y=24 [from 1]
y=8........(2)
so
x=2.8 [from 1 &2]
x=16
