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
The perimeter is the distance all the way around. So it's the sum of the lengths of all 4 sides.
From the picture, you can clearly see the lengths of all 4 sides.

Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55
Think of "of" as times, so you are finding out what multiplies by 106% to get 7.95.
$7.95 divided by 1.06 = $7.50
106% of $7.50 = $7.95
