Answer:
Kenyan French Roast coffee x=6
Sumatran coffee y=14
Step-by-step explanation:
x+y=20 blend coffee
8x+7y=7.3(20) selling price
x+y=20 ⇒ x=20-y
substitute in the equation:
8x+7y=7.3(20)
8(20-y)+7y=7.3(20) for 20 pound blend
160-8y+7y=146
-y=146-160
y=14 pond
x+y=20
x=20-14=6
check : 14*7+6(8)=146/7.3=20 pound
<span>That depends on what you mean by "pound" and "ounce."
There are 16 English ounces in an English pound. There are 12 troy ounces in a troy pound.</span>

7(x-1)=70/10
7x-7=7
7x=14
x = 2
The number is 2.
