Fabulous Fabrics budgeted to manufacture 1300 curtains in February. Actual output for March was with total direct materials cost of $3700 and total direct labor cost of $5250. The direct labor standard is 20 minutes per curtain at a direct labor rate of $15.50 per hour. The direct material standard is 0.75 yards of direct materials per curtain at a cost of $11 per pound. Actual direct labor hours were 150.
A variance analysis for February may show a direct labor rate variance of . (Round any intermediary calculations and your final answer to the nearest cent.)

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
