Give the step-by-step reasoning process and then the final answer. On Thursday the Meat Market sold 210kg of ground beef. On Friday they sold twice that amount. On Saturday they only sold 130kg. On Sunday they sold half of what they sold Saturday. If they originally planned to sell only 500kg, how much meat did they sell beyond their original plans?
On Friday they sold 210 × 2 = 420kg. On Sunday they sold 130 ÷ 2 = 65kg. They sold a total of 210 + 420 + 130 + 65 = 825kg of meat. Meat Market sold an extra 825 - 500 = 325kg of meat beyond their original 500kg plans.
The final answer: 325.
