I need help. I know the formula for Quantity variance is (Actual price-Standard Price) x Actual quantity. But I don't know how to calculate actual price.

The following information is for the standard and actual costs for Chesapeake Bay Corporation.

Standard Costs:

Budgeted units of production - 16,000 (80% of capacity)

Standard labor hours per unit - 4

Standard labor rate $26 per hour

Standard material per unit - 8 lbs.

Standard material cost - $ 12 per lb.

Budgeted fixed overhead $640,000

Standard variable overhead rate - $15 per labor hour.

Fixed overhead rate is based on budgeted labor hours at 80% capacity.

Actual Cost:

Actual production - 16,500 units

Actual fixed overhead - $640,000

Actual variable overhead - $1,000,000

Actual labor - 65,000 hours, total labor costs $1,700,000

Actual material purchased and used - 130,000 lbs, total material cost $1,600,000

Actual variable overhead - $1,000,000

Determine: (a) the quantity variance
