Answer:
1
Step-by-step explanation:
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
1/2 = 50%
1/4 = 25%
1 = 100%
1/3 = 33.3%
The only one that makes sense is 1/3

25%
Because 25% (1/4) of four is 1/1 or simply just 1. Now if we subtract 1 from 4 we get 3. This is the same as subtracting 25% from four.
To find the percentage of a number thorn the percentage into a fraction and multiply them together. e.g. 1/4 * 4 = 4/4 = 1
