Setting Standards, Materials and Labor Variances Tom Belford and Tony Sorrentino own a small business devoted to kitehen and bath granite installations, Recentiy, building contractors have insisted on up-frent bild prices for a house rather than the cost-plus system that Tom and Tony had been using. They worry because natural flaws in the granite make it impossble to tall in advance exactly how much granite wilt be used on a particular job. In addition, granite can be ensily broken, meaning that Tom or Tony could ruin a stab and would need to start over with a new one. Sometimes the improperly cut pleces could be used for smaller installations, sometimes not. All their accounting is done by a local certified public accounting firm neaded by Crarlene Davenport. Charlene listened to their concerns and suggested that it might be time to implement tighter controis by setting up a standard costing system. Charlene reviewed the invoices pertaining to a number of Tom and Tony's previous jobs to determine the average amount of granite snd glue noeded per square foot. She then updated prices on both materials to reflect current conditions. The standards she developed for 1 square foot of counter installed were as follows: These standards assumed that one seamiess counter requires one sink cut (the space into which the sink will fit) as well as cutting the counter to fit the space avalable. Charinne tracked the actual costs incurred by Tom and Tony for granite installation for the next 6 moaths. She found that they completed 50 jabs with an average of 32 square feet of aranite installed in each one. The foliowing information on actual amounts used and cost was gathered: The actual wage rate for cutting and installation labor remained unchanged from the standard rate. Required: If an amount is zero, enter " 0 - and seiect neither from the dropdown. 1. Caiculate the materiais price variances and materiais usage variances tor granite and for glue for the past six thonths. 2. Caiculate the labor rate variances and labor efficiency varances for cutting labor and for instatiation labor for the past six menths 3. Conceptual Connection: Would it be worthwhile for Chariene to establish standards for atypical jobs (such as those with more than one sink cut or wider than norinali
