Explanation:</h2><h2>
</h2>
Here we need to set a system of two linear equations in two variables. So:
- <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>
Let
be those digits, then:

- <em>If 9 is added to a number then both the digits become equal. find the number:</em>
<em />
<em />
<em />
<em />
But from eq 1:

Substituting y into the expression 1:

The x-value will be found by hit and trial, so:

We have to reject this solution because digits are different.

We have to reject this solution because digits are different.

<em>Then this is a two digit number formed by two equal digits. </em>
Finally, the number is:
44
Options:
a. Balance Transfers
b. Cash Advances
c. Payments
d. Interest Charges
Answer:
c. Payments
Step-by-step explanation:
Of all the given options, only (c) Payments decreases amount owed.
(a) Balance transfer means one is taking out cash from the account (i.e. a debit transaction); (b) Cash advances implies a withdrawal transaction from one's account and (c) Interest charges is the amount of interest deducted from an account over a debt for a given period.
As analysed , each of the above transactions increases debts.
However, (c) Payments implies a credit transaction and as such, reduces the amount owed.
