Given parameters:
Cost per pound of Arabica coffee = $28 per pound
Cost of Robusta coffee = $8.75
Given number of pounds of Robusta Coffee = 3 pounds
Total cost of blend per pound = $15.50
Unknown:
Number of pounds of Arabica coffee = ?
Solution:
Let the number of pounds of Arabica coffee = A;
We have to interpret this problem algebraically and solve;
28A + 8.75(3) = 15.5(A + 3)
Now solve the expression above for A;
28A + 26.25 = 15.5A + 46.5
28A - 15.5A = 46.5 - 26.25
12.5A = 20.25
A = 1.62
Number of pounds of Arabica Coffee is 1.62 pound
12/15 = 400/500

Answer:
the number is greater than the variable.
Step-by-step explanation:
Answer:
y = 2/5x + 12/5
Step-by-step explanation:
Let's solve for y.
2x−5y=−12
Step 1: Add -2x to both sides.
2x−5y+−2x=−12+−2x
−5y=−2x−12
Step 2: Divide both sides by -5.
−5y/−5 = −2x−12/−5
y = 2/5x + 12/5
