Cassandra works at a bookstore. Yesterday, she sold 18 hardcover books. The rest of the books she sold were paperback books. She sold a total of 41 books. How many paperback books did she sell?
Use the variable p to represent the number of paperback books Cassandra sold yesterday.
Which equation represents this situation and its solution?
p + 18 = 41; p = 23
18p = 41; p = 23
p + 41 = 18; p = 23
41p = 18; p = 23
