To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets to bytes of nformation is given by $b=1,500 p$ where $p$ represents the number of packets and $b$ epresents the number of bytes of information. a. How many packets would be needed to transmit 30,000 bytes of information? b. How much information could be transmitted in 30,000 packets? c. Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the number of bits.
