Answer:
35 > y. 36 is not a possible solution
Step-by-step explanation:
Answer:
x^2+2xy+y^2
Step-by-step explanation:
(x + y)(x + y)
FOIL
first x*x = x^2
Outer x*y = xy
inner: y*x = xy
last y*y = y^2
add together
x^2+xy+xy+y^2
Combine like terms
x^2+2xy+y^2
The customer bought 0.25 pounds of Sri Lankan coffee and 3.75 pounds of Kona coffee
Data;
- Kona (y) = $6.20
- Sri Lankan (x) = $4.20
<h3>System of Equation</h3>
To solve this question, let us write a system of equations to show this problem.

From equation (i)

Put equation (iii) into equation (ii)

Using the value of y which is the Kona's coffee, let's substitute this into equation (i) to solve for x

From the calculations above,
- The amount of Sri Lankan coffee = 0.25 pound
- The amount of Kona coffee = 3.75 pounds
