Answer:
if im not mistaken.. i would say its -3.5 or -7/2
Step-by-step explanation:
Rational it stops and repeats
Part A:
Given that <span>a dinette table with a cash price of $200 is purchased at $8.50 down and $11.00 per month for 24 months
The total installment price is given by

Part B:
The carrying charges is given by the total installation price minus the cash price.
From part a, we obtained that the total installation price is $272.50 and given that the cash price is $200.
Therefore, the carrying charges is given by
$272.50 - $200.00 = $72.00
Part C:
If the money is to be saved at $11 per month to be able to purchase the table at the cash price, the number of months it will take to be able to save $200 at $11 per month is given by

Therefore, it will take 19 months </span><span>to save the money at the monthly rate needed to buy the item for its cash price.</span>
Take this example (cause it's easy to explain)
10+5x=15x
To solve it we have to minus five on both side. We have to do this because we need to isolate the variable (in this case x) on the one side so we can divide and solve.
You would -5x (inverse from positive 5) from both sides on this because whatever you do to one side you have to do to the others to make it equal. In this case the answer would be x=1 (again cause it's easy lol.)
I hope this helps you!
