A coffee shop sells a special blend of coffee that is made by mixing two types of coffee beans: Type A and Type B. The shop sells Type A for $8 per pound and Type B for $12 per pound.
On Monday, the shop used a total of 10 pounds of coffee beans, consisting of Type A and Type B. If the total cost of the coffee beans used on that day was $92, how many pounds of Type A coffee beans were used?
