9.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
p + 41 = 18; p = 23
41p = 18; p = 23
18p = 41; p = 23
