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

J(4x7)
Answer:
Y= 2x+3
Step-by-step explanation:
The Slope-Intercept formula is y=mx+b. M is the slope, b is the y intercept, x is the independent variable and y is the dependent variable. In order to write an equation for these types of problems, plug in the numbers for the variables.
P=2(l+w) hope this helps :)
Answer:
Step-by-step explanation:
(4,1/3) and has a slope of 3/4
y - y1 = m(x - x1)
m = 3/4, y1 = 1/3, x1 = 4
y - 1/3 = 3/4(x - 4)
Multiply each term by 12
12y - 4 = 9x - 36
12y = 9x - 36 + 4
12y = 9x - 32
