(x,y): (6 , -3) or (-30/7 , 33/7)

Step-by-step explanation:

6x + 8y = 12

x = y + 9 or y = x+ 9

if x = y+9

6*(y+9) + 8y = 12

14y = -42

y = -3 and x = 6

if y = x+9

6x + 8*(x+9) = 12

14x = -60

x = -30/7 and y = 33/7

#6) Which of the following is not an example of a contract?

Out of all the options that are presented above the one that is not an example of a contract is D) Borrowing lunch money. A contract not only has to be between two or more parties but, it must also be enforceable by the court of law.

#8) The United States Treasury issues ___ for you to purchase.

It issues C) Saving bonds for you to purchase.

#9) You want to buy a used car for $8,648.00 plus 4.7% sales tax. You want to make a 5% down payment. How much is your down payment?

After calculating the total cost of the car including sales tax I got $9054.47. The amount of money for your down payment of 5% is $452.723, leaving you with a loan of $8601.747.

#10) You want to buy a house in 9 years. The estimated cost is $175,800.00. You want to make a 20% down payment and closing costs are 7%. How much in total do you need save each month to reach your goal if you cover closing costs and the down payment?

For the 20% down payment we have $35,160 and for the closing cost $12,306. We know that 9 years have 108 months. With this information we get that we will need to save $325.56 each month for the down payment and $113.94 each month for the closing costs.

#11) You save 15% of your realized income each week. How much do you save per month?

After calculating the total money made hourly we get a total of $8.55. This means that we make a total of $111.15 a week. The total percentage of taxes is 28.15%. Our net is 71.85%. That leaves us with total of $79.86 dollars weekly. Now to calculate our savings weekly we take $79.86 and multiply it by 15% and we get $11.98 as our weekly savings. The total amount of money we get to save per month is $47.92.

#12) How much is the total value of your stocks in the second year?

Okay so first we have to know the total number of shares that we bought. For this we simply take our investment and divided by $10/share. We get 105. Then we calculate the value of our shares for the first year which would be $11.3 and after two years $10.735 because it decreased by 5%. As a result our total value of stocks in the second year is $1127.175.

#13) What is the difference in earnings between the stock and savings account the end of the second year?

After calculating the stock and savings account total I found out that the difference in earning between them is $104.738.

#14) How much is the difference and payments is you stay the whole year?

All we have to do is calculate the total amount of the lease which is $502*12 = $6024. Then the month to month contract which is $615*12 = $7380. From here we simply subtract to get the difference in payment if you stay the whole year. The difference is $1356.

#15) Using the information from number 14, you leave after six months. How much is the difference in that amount paid between the two contracts?

For this case we will have to take into account the penalty for breaking the lease. So for the lease we will get $4016 and for the month to month contract we get $3690. The difference is $326.

I hope it helps, Regards.
