suppose you can buy chocolate bars from a vending machine for $1 each. inside every chocolate bar is a coupon. you can redeem 7 coupons for 1 chocolate bar from the machine. for example, if you have $20, you can initially buy 20 chocolate bars. this gives you 20 coupons. you can redeem 14 coupons for 2 additional chocolate bars. these 2 chocolate bars have 2 more coupons, so you now have a total of 8 coupons. this gives you enough to redeem for 1 final chocolate bar. write a recursive function that would accept the amount of dollars and coupons as its parameters and output the total number of chocolate bars that can be bought (including those redeemed via coupons). write a test program that would allow the user to enter amount of dollars and then use the recursive function to compute the number of chocolate bars the user can buy, and output the number to the screen.

The statement "RFID eliminates the need for manual counting and bar-code scanning of goods at receiving docks" is a true statement. This is because RFID technology can assist cashiers in scanning codes on products purchased by customers so that their work can be assisted

Radio Frequency Identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a small radio transponder, a receiver and a radio transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader, the tag transmits digital data, typically an identifier number, to the reader. This number can be used to track goods in stock.

Passive tags are powered by interrogating radio wave energy from an RFID reader. Active tags are battery-powered and can therefore be read at longer distances than RFID readers, up to hundreds of meters. Unlike barcodes, tags do not need to be in the reader's line of sight, so tags can be embedded in the tracked object. RFID is an automated identification and data collection (AIDC) method.

It takes the faster computer 70 minutes to do the job on its own.

To solve this problem, we can use the formula for solving for the time it takes two people working together to complete a task:

Time = (Time of slower worker * Number of workers) / (Number of workers - 1)

This formula is based on the idea that the slower worker determines the overall time it takes to complete the task, and the faster worker helps to reduce the overall time. The formula takes into account the time that the slower worker takes to complete the task on their own, as well as the number of workers involved.

In this case, we are given that it takes the slower computer 35 minutes to do the job on its own, and that it takes the two computers working together 10 minutes to send out the company's email. We can plug these values into the formula as follows:

Time = (35 minutes * 2) / (2 - 1)

= 70 minutes / 1

= 70 minutes
