A certain store purchased grills for $50 each and lawn chairs for $5 each and then sold each grill and each chair. The store's gross profit on each grill was 30 percent of its purchase price, and the store's gross profit on each chair was 50 percent of its purchase price. If the store sold 5 times as many chairs as grills and if the store's total gross profit on the grills and chairs was $550, what was the store's total revenue from the sale of the grills and chairs?
