A)
The lawyer in 20 years earns 3,620,000
The mathematician in 40 years earns 3,160,000
Subtract to find the difference:
3,620,000 - 3,160,000 = 460,000
The answer is the first one.
B)
Interest would be a credit of 27.23, balance = 700 + 27.23 = 723.23
Transfer would be a debit of 176.02 balance = 723.23 - 176.02 = 547.21
Deposit would be a credit of 157.00 balance = 547.21 + 157.00 = 704.21
A check would be a debit of 47.13 balance = 704.21 - 47.13 = 657.08
