We first start off with the equation \(450 * .005 = X\). X stands for the total amount he pays every 7 days.
X=2.25 dollars.
If he has paid back 18 dollars already, then we can divide the amount he pays (2.25) by 18 to get how many weeks he has paid so far.
\(18 / 2.25 = 8\)
He has paid for 8 weeks. Since the question is asking for days, we multiply 8 by 7 to get the answer.
8 * 7 = 56
The correct answer is E.
X=2.25 dollars.
If he has paid back 18 dollars already, then we can divide the amount he pays (2.25) by 18 to get how many weeks he has paid so far.
\(18 / 2.25 = 8\)
He has paid for 8 weeks. Since the question is asking for days, we multiply 8 by 7 to get the answer.
8 * 7 = 56
The correct answer is E.

Explanation
1% of $450 is $4.50, so 0.5% is $2.25. That’s the amount Raymond pays back every week.
Because he has paid back $18 in total, divide 18 by 2.25 to determine the total number of payments:
\(\frac{18}{2.25}= 8.\)
So Raymond has made 8 payments, once every 7 days. The payments themselves spread over only a 7-week period (in the same way that 2 payments spread over only a 1-week period).
Raymond waited 1 week to begin repayment, however, so a total of 8 weeks, or 56 days, have passed since he borrowed the money.
1% of $450 is $4.50, so 0.5% is $2.25. That’s the amount Raymond pays back every week.
