Bally Manufacturing sent Intel Corporation an invoice for machinery with a $13,200 list price. Bally dated the invoice August 02
aliya0001 [1]

a. Based on the information the amount that Intel pay Bally on August 15 is $10,400.

b. The payable amount is $10,192.

a. Intel pay Bally on August 15:

First step is to calculate the 20% trade discount applied to gross invoice

20% trade discount applied to gross invoice =($13,200-$200) × 0.2

20% trade discount applied to gross invoice = $13,000×0.2

20% trade discount applied to gross invoice=$2,600

Second step is to calculate Net price after trade discount

Net price after trade discount = ($13,200-$200) - $2,600

Net price after trade discount =$13,000-$2,600

Net price after trade discount = $10,400

b. Payable amount:

Payable amount= $10,400-( $10,400×2%)

Payable amount=$10,400-$208

Payable amount=$10,192

Inconclusion the amount that Intel pay Bally on August 15 is $10,400 and the payable amount is $10,192.

Luden [163]
This is not a full question.  If you were given the amount at the begining of 1970 (we'll call it x) and the amount at the end of 1980 (we'll call it y), we should solve them accordingly:
y-x=? (calling the answer a)
a/y=%(not answer yet, call this b)

A rectangular prism is packed with cubes that measure 1/4 inch on each side
AveGali [126]
This doesn't have enough information to solve the problem, like what the length or width, or how many cubes are in the length, or something. Not enough information leads to nobody being able to solve it

How do I solve this?Farmer Ed has 1500 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If fa
Dafna1 [17]

We need to find the maximum (Vertex of the function)

Let:

L = Length = 1500 - 2x

W = Width = x

The area is given by:

\begin{gathered} A=W\cdot L \\ A=x(1500-2x) \\ A=1500x-2x^2 \\ A(x)=1500x-2x^2 \end{gathered}

We can find the maximum using the following formula:

\begin{gathered} xm=-\frac{b}{2a} \\ where \\ a=-2 \\ b=1500 \\ so\colon \\ xm=-\frac{(1500)}{2(-2)}=\frac{1500}{4}=375 \end{gathered}

Evaluate the area for the value we found previously:

A(375)=-2(375)^2+1500(375)=-281250+562500=281250

The largest area that can be enclosed is 281250m²
