The standard price per gallon is $\$ 3.15$ Compute the following variances:

1. The materials price variance if the chemical is carried in inventory at standard price 2. The materials price variance if the chemical is carried in inventory at actual price and is charged to Work-in-Process Inventory at the standard price
