Answer:
$401.55
Step-by-step explanation:
Given:
Pat's ending balance on his debit card last month was $233.55,<u> we can consider it as opening balance for this month as carry forwarded.</u>
This month he had $542 worth of purchases.
This month he had $710 worth of deposits.
Question asked:
What is his ending balance for this month ?
Solution:
We can easily find the ending balance by subtracting purchase amount as it will reduce the balance and we will add deposits as it increase the balance of debit card.
Opening balance of debit card = $233.55
Purchases worth of = $542
Deposit worth of = $710
<em><u>Ending balance for this month = Opening balance of debit card + Deposit - Purchases </u></em>
Ending balance for this month = $233.55 + $710 - $542
= $943.55 - $542 = $401.55
Therefore, the ending balance for this month in his debit card is $401.55
Answer:
Each Friend will get 
cards.
Step-by-step explanation:
Let the number of cards be x.
Given:
Amount Nicole used to spend on cards = $9
Total cost of one set =$27
Also, she finds friends with the same amount of money to split the cost of a set.
So, Number of friends she finds can be calculated by dividing the Cost of 1 set with amount of money Nichole used to spend on cards.
Number of friends she finds = 
Hence she finds 2 friends and 1 is nichole hence there are 3 persons carrying $9 to buy $27 set of card
Now, Number of cards each friend gets is equal to Total number of Cards in 1 set divided by number of people.
Number of cards each friend =
Hence Each Friend will get cards.
in the equation as we can say x= 2y-10.
so, substitute x=2y-10 everywhere then the x in 1240 gets cancelled with 2y-10 then solve the remaining you will get 4y-20+3y=1240
7y=1260
y=1260/7
y=180
then substitute the value of y everywhere
2x+3y=1240
2x+3(180)=1240
2x=1240-540
2x=700
x=350
DONE.
