Answer:
Explanation:
A publisher sells digital copies of their new book, paperback copies or barnacle copies.
Digital sales = d
Paper back sales = p
Hard back sales = h
For every 4 digital sales they make, they make 5 paperback sales and 1 hardback sale.
In the first week of sales, the company sells 307 more paperback copies of the book than hardback copies.
p = 307 + h
How many total copies of the book did the company make in week 1?
