The following invoice contains the notation "2/10, n/30." Determine the price of the order. An invoice dated December 27 lists a

irinina [24]

Answer:

The problem statement tells you the order price is $885.00.

The balance to be paid on 5 Jan is 2% less than that, $867.30.

Step-by-step explanation:

The notation "2/10, n/30" means a discount of 2% is applied if the invoice is paid within 10 days, but the net amount is due within 30 days in any event. 10 days after 27 Dec is 6 Jan, so a payment on the 5th of January is subject to the 2% discount.

After 2% is subtracted from 100% of the invoice amount, 98% percent remains. The payment need only be ...

... 0.98 × $885.00 = $867.30

Comment on problem wording

Your problem statement says, "Determine the price of the order." It also says, "... an order priced at $885.00." The determination asked for is found in the problem statement: $885.00. If that is the required answer, it would place this problem in the "trick question" category, as the notation and payment date information are clearly unneeded.

We suspect the problem really wants you to determine the amount to be paid for the order when payment is made on January 5. Unfortunately, that is not what is asked for.

Graph a line that contains the point (-5,-3) and has a slope of -2

Tpy6a [65]

Answer:

-->

Step-by-step explanation:

Graph (-5,-3) and use the slope, -2, to find another point. -2 can also be written as $-\frac{2}{1}$

$\frac{rise}{run} =\frac{-2}{1}$ and $\frac{rise}{run} =\frac{2}{-1}$ **

Use both. This works because either way, they will lie on the same line with the same slope. So, starting at (-5,-3), go down two points (-)* and to the left 1 (+)*, then, starting at (-5,-3) again, go up two points (+)* then to the right 1 point (-)*.

* If the number is negative, you either go down or to the right. If the number is positive, you go up and to the left.

**Rise over run refers to the change in the y-axis and the change in the x-axis: $\frac{rise}{run} =\frac{y-axis}{x-axis}$ . Only one number is negative because, if both were negative, that would make a positive number, but the slope is -2, not 2.
