Final answer:
After converting the weights to decimals, Karl bought 13.11 pounds of pork by subtracting the weight of the beef (9.25 pounds) from the total weight of meat (22.36 pounds).
Step-by-step explanation:
To find out how many pounds of pork Karl bought, we need to subtract the weight of the beef from the total weight of the meat he left with. Karl bought 9 1/4 pounds of beef, which is 9.25 pounds when expressed as a decimal. He left with 22 9/25 pounds of meat in total, which is 22.36 pounds when converted to a decimal. The calculation to find the weight of the pork is as follows:
Total weight of meat - Weight of beef = Weight of pork
22.36 lb - 9.25 lb = 13.11 lb
Therefore, Karl bought 13.11 pounds of pork.
