Janice brought a set of 8 classic paperbacks to a secondhand store to sell. She was paid cash
for the entire set. Before she left, Janice used $4 of her earnings to purchase a used board
game. She had $10 remaining.
Which equation can you use to find p, the value of each paperback in the set?
4p - 8 = 10
8p - 4 = 10
8(p-4)= 10
4(p-8)= 10
