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
![P=\$8.50+\$11(24) \\ \\ =\$8.50+\$264=\$272.50](https://tex.z-dn.net/?f=P%3D%5C%248.50%2B%5C%2411%2824%29%20%5C%5C%20%20%5C%5C%20%3D%5C%248.50%2B%5C%24264%3D%5C%24272.50)
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
![\frac{\$200}{\$11} =18.18\, months](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5C%24200%7D%7B%5C%2411%7D%20%3D18.18%5C%2C%20months)
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>
Side AB and side AD are perpendicular because they cross at a ninety degree angle, and the sides are also the same length.
<span>120/x - 120/(x+10) = 1
120x + 1200 - 120x = x(x+10)
1200 = x^2+10x
x^2 + 10x - 1200 = 0
(x+40)(x-30) = 0
Positive solution:
x = 30 km/hr (rate on the 1st trip)
x+10 = 40 km/hr (rate on the return trip)</span>
9 numbers and 5 are even. 5/9 5 divided by 9 is .55 continued. So it would be estimated as 55.5 %
