Why might a researcher use a variable ratio of reinforcement rather than a fixed ratio?

Why might a researcher use a variable ratio of reinforcement rather than a fixed ratio? Correct Answer Variable ratio schedules of reinforcement are more resistant to extinction than fixed schedules.

(E) Organisms trained using variable ratio schedules of reinforcements will continue to perform the desired behavior for a long time after reinforcement is stopped (i.e., extinction of the behavior is delayed).

"S produces and sells one product, P, for which the data are as follows:
Selling price Rs 28
Variable cost Rs 16
Fixed cost Rs 4
The fixed costs are based on a budgeted production and sales level of 25,000 units for the next period. Due to market changes both the selling price and the variable cost are expected to increase above the budgeted level in the next period. If the selling price and variable cost per unit increase by 10% and 8% respectively, by how much must sales volume change, compared with the original budgeted level, in order to achieve the original budgeted profit for the period?"
