8.9 pounds of coffee A, 27.3 pounds of coffee B and 17.8 pounds of coffee C are need to make a blend that sells for $12.61 per pound.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent coffee A, y represent coffee B and z represent coffee C, hence:
x + y + z = 54 (1)
Also:
2x = z (2)
And:
15.21x + 13.21y + 10.39z = 12.61(54) (3)
x = 8.9, y = 27.3 and z = 17.8

(X+y)^2(x+y)^2
(X^2+2xy+y^2)(X^2+2xy+y^2)
X^2(x^2+2xy+y)+2xy(x^2+2xy+y)+y^2(x^2+2xy+y)
X^4+4x^3y+6x^2y^2+4xy^3+y^4 is the answer.i didn't write all the steps as I would have been too long and complicated
Answer:

Step-by-step explanation:
Answer:
$637.5
Step-by-step explanation:
Given data
Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount
=15/100*750
=0.15*750
=$112.5
Hence the amount paid will be
=750-112.5
=$637.5
