Answer:
Ryan's revenue last month if he sold 16 new books and 25 old books
is $337.50.
Step-by-step explanation:
The number of old books sold by Ryan = 25
The cost of each old book = $5.50
⇒ Total amount earned by selling 25 old books = 25 x $5.50
= $137.5
The number of new books sold by Ryan = 16
The cost of each new book = $12.50
⇒ Total amount earned by selling 16 new books = 16 x $12.50
= $200
Hence Total amount earned by Ryan
= Amount earned by selling old books + Amount by selling new books
= $137.5 + $200
= $337.50
or, Total amount earned by Ryan = $337.50
Hence Ryan's revenue last month if he sold 16 new books and 25 old books is $337.50.
