Arabica coffee costs $28 per pound and Robusta coffee
Soloha48 [4]

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

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
