Final answer:
If a loan is offered with an interest rate of 4.25% and you borrow $4.25, then the interest you would need to repay after one week is $0.18. The total amount you would need to repay is $4.43.
Step-by-step explanation:
If a loan is offered with an interest rate of 4.25% and you borrow $4.25, then the interest you would need to repay is calculated as follows:
Interest = Loan Amount × Interest Rate = $4.25 × 0.0425 = $0.18
So, the total amount you would need to repay after one week would be $4.25 (loan amount) + $0.18 (interest) = $4.43.
