INSTRUCTION YOU NEED TO MODIFY BANK ACCOUNT UNDER ACCEPT Y WHERE IT WILL ONLY ACCEPT BANK ACCOUNTS OF VALUES OF 1000 OR MORE AND UNDER THE DATA FILE YOU WILL NEED TO FIND THE SUM OF THE BANK ACCOUNTS THAT IS 1000 OR MORE FOR AN EXAMPLE MY TEST FILE IT HAS ACCOUNT 1 = 0 AND ACCOUNT 2 = 10000 AND ACCOUNT 3 = 2000 SO IT WILL GET ACCOUNT 2 AND ACCOUNT 3 DIVIDE THE NUMBER OF ACCOUNTS SO 2 ---> (10000+2000)/2=6000 SHOULD BE OUPUT ONLY NEED TO MODIFY ^^^^ DOES FILES

output should be

Average balance: 2000.0 Expected: 2000 Average area: 239950.0 Expected: 239950

2000 + 2000/2 = 2000

if you dont have that don't post the answer show output for a upvote
