Answer:
1. The actual cost for hours worked less the budgeted cost for hours worked is;
= Actual cost - Budgeted cost
= 4,000,000 - 4,500,000
= -$500,000
2. .This tells you that the actual cost at actual hours worked is (B.) less than the budgeted cost at actual hours worked.
The actual cost was $500,000 less than the cost that was budgeted.
3. What type of variance is this? (A.) Favorable rate variance
When actual activity costs less than the amount that was initially planned for the activity (budgeted amount), a favorable variance exists.
