Answer:

Led Tube Lights

Explanation:

Tubular lamps are commonly used in spaces where lighting is needed for long periods of time. Therefore, one of the most important factors for store managers when choosing the most appropriate type of lamp is their consumption.

The difference between LED tubes and fluorescent tubes is significant, although not apparent when comparing the consumption of only one lamp. However, when making the calculation considering the total number of them, the energy consumption of fluorescent lights can even double.

Other benefits of LED tube

Turn on instantly; does not require reactors, consuming less energy;

Unlike fluorescent, it does not emit ultraviolet and infrared rays;
Can have up to 50,000 hours of service life, reducing the need for maintenance;
It is made of sturdy material and can withstand shock and vibration;
Its intensity can be controlled;
Opens up the possibility of implementing sensors.

Goal Seek Parameters and Results

Set Cell C14

To Value By Changing Cell 2625000

By Changing Cell C3

Resulting Price? $290

Explanation:

The goal seek tool in excel is used to change a value in the calculation to get the desired results.

In the given question, it is required to get the demand of tablets to reach the value of 2,625,000 by changing the price.

The value that is to be inserted in the “Set cell” field is the cell number which shall contain the desired result. This cell must have a formula having the cell which is inserted in the “by changing cell” field.

In the given question, the value of demand is desired.

The cell value which stores the calculated demand is C14 is and hence it is inserted in the field “Set cell”

The “to value” field of the goal seek tool is used to set the desired result.

Here, 2,625,000 is the value that is desired and hence it filled in the “To value” field.

The “By changing cell” field of the goal seek tool, represents the cell whose value is to be changed for getting the desired results.

Here, the value of price is required to be changed to get the required demand, thus the value that should be inserted in the “By changing cell” of the goal seek tool is C3, which represents the price.

The required demand is achieved by changing the price to $290.

As a visually disabled person my self (if you want to check it out I have something called Aniridia) I love when websites have tabs easy to identify each category of the website. Additionally, when websites have clear bold titles and not to many words close together (it really do be putting strain on ones eye when that happens so having separated paragraphs is awesome if the website has words) but other than that it’s all I could think of from my POV. Hope this helps you :)
