Need help with understanding the prcoess behind variance, I'm used to solving it in a different format, please help

Compute the following variances:

1. material variance (price and quantity) I got 5,720 U for material price variance, not sure if this is correct

2. labor variance (rate and efficiency)

3. variable overhead variance (spending and efficiency)
