Final answer:
On Friday, they sold 290 pounds more meat than on Saturday.
Step-by-step explanation:
To find out how much more meat was sold on Friday than Saturday, we need to subtract the amount of meat sold on Saturday from the amount sold on Friday. On Thursday, 210 pounds of ground beef were sold. On Friday, twice that amount was sold, which is 2 x 210 = 420 pounds. On Saturday, 130 pounds were sold. Therefore, the difference between the amount of meat sold on Friday and Saturday is 420 - 130 = 290 pounds. So, they sold 290 pounds more meat on Friday than on Saturday.
