Can you help me solve this general accounting question using valid accounting techniques?

Blair Equipment Co. of New Zealand manufactures outdoor gear. One of the company's products, a hiking backpack for the Asian market, requires a special nylon fabric. During the quarter ending June 30, the company manufactured 4,200 backpacks, using 3,150 meters of fabric. The fabric cost the company $24,570. According to the standard cost card, each backpack should require 0.72 meters of fabric, at a cost of $7.50 per meter. According to the standards, what cost for fabric should have been incurred to make 4,200 backpacks? How much greater or less is this than the cost that was incurred?
