When thinking about reinforcement, always remember that the end result is to try to increase the behavior, whereas punishment procedures are used to decrease behavior. For positive reinforcement, try to think of it as adding something positive in order to increase a response.

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
