Answer:
c.could have deposited less money today and still had $5.000 In four years If the account paid a higher rate of interest.
Explanation:
Since the Sam has opened a saving account and paying 3.5% interest compounded annually and after four years the amount of saving account is $5,000
So according to this given data, the Sam should do deposited the less money today and can be $5,000 in four years if the account gives a higher rate of interest
The other options are wrong because in the first case, the same amount in compounding earns higher interest rate as compared to the previous years and other two options will also not give such higher rate of interest
