____________________ is like a set of instructions that helps hardware process data into information.
Arte-miy333 [17]

Answer:

Program

Explanation:

Program is like a set of instructions that helps hardware process data into information.

Every hardware needs a program to process data into information.

For example take the example of a data processing software like MS Excel.

You open a spreadsheet and enter some data into your sheet. and then ask the program to do some calculations with this data and give you output results. The spreadsheet software does this processing in the background for you and provides you the results.

Without program a hardware doesn't know what to do with the data. Therefore, a program is like a instruction set that guides the hardware what to do with the data.

Note: The terms software and program are usually used together but there is a difference between software and program

A software is a generalized term and program is more like a specific term.

software can be made up of several different programs which performs many different tasks. On the other hand, a program only carry out a specific task or set of instructions.

b. $2,300

<u>Explanation:</u>

Consumer surplus can be defined as the amount that the consumer is willing to pay for a product or a service. The word surplus is a synonym for something extra or excess. It corresponds to the extra benefit that the consumer gets while buying something which may be the result of some discount, sale, or negotiation.  

Jeff realizes a consumer surplus of $700 while purchasing a laptop of $3000. As the consumer surplus is $700,

the amount Jeff has paid for the laptop is: $3000 - $700

                                          : $2300
