Find the values of the missing items. Assume that actual sales volume equals actual production volume. (There are no inventory level changes.) (Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.)
