Compute the materials price and quantity variances. (Indicate the effect of each variance by selecting "F" for favourable, "U" for unfavourable, and "None" for no effect (i.e., zero variance). Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your final answers to the nearest dollar amount. Omit the "$" sign in your response.)
