Budgeted sales units                               3,600

Actual sales units                                     5,000

Sales volume                                             1,400

Standard profit per unit                            × $1.7

Sales volume variance                            2,380 Favorable

Sales volume variance $2,380 favorable

The net effect on profit of AR-10's sales is that it will increase profit by $2,380
