Answer:
a) B
b) B
Step-by-step explanation:
Let's calculate the amount in each account after one and two weeks to see which has more money:
Account A:
Starts with $5000.
Doesn't change weekly (grows annually).
So, after one week and two weeks, Account A still has $5000.
Account B:
Starts with $1.
Doubles each week.
After one week, it'll have $1×2
= $2.
After two weeks, it'll have $2×2
= $4.
Comparison:
After one week, Account B has more money ($2) than Account A ($5000).
After two weeks, Account B still has more money ($4) than Account A ($5000).
Therefore, even though Account A has a much larger initial amount, Account B's exponential growth makes it have more money after one and two weeks.
Note:
Here Bank didn't give interest weekly.
