Answer:
Bank One is offering a simple interest rate of 6.25% per annum.
Step-by-step explanation:
Given that Bank One offers a certificate of deposit that pays $ 5,000 in four years for exchange for $ 4,000 today, to determine what interest rate is Bank One offering the following calculation must be performed:
(5000 - 4000) / 4 = X
1000/4 = X
250 = X
4000 = 100
250 = X
250 x 100/4000 = X
25000/4000 = X
6.25 = X
Therefore, Bank One is offering a simple interest rate of 6.25% per annum.

Answer: 3 quart
Step-by-step explanation:
Given
Jason poured 1 gallon 1 quart of water into an empty 2 gallon bucket

So, 2 gallon can be written as 8 quart
Subtract 1 gallon 1 quart(5 quart) from 2 gallon(8 quart) to get the volume added

So, 3 quart of water must be added to reach 2 gallon capacity.
