Find the values of the missing items. Assume that the actual sales volume equals actual production volume. (There are no inventory level changes.)(Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Do not round your intermediate calculations.)
