Free$-$response question # $7$ is based on the following information:

Anastasia Corporation uses standard costing. The pre$-$determined rate for variable manufacturing overhead is $$5$ per machine hour. Anastasia budgeted to make $100$ units this month. Each unit produced should take $10$ machine hours. Actual output was $105$ units and the number of machine hours used was $1,080.$ Actual variable manufacturing overhead cost were $$4,900.$

Was variable manufacturing overhead over or under applied and by how much?
