If half of Karen's collection (4) is 1/3 of Mary's, and half of Karen's collection is 2, then 2 x 3 is how many Mary has, right? Once you know how many books Mary has, you can add how many Karen has to get your answer.

Answer:
A.
x + y = 28
1.68x + 2.44y = 54.64
Step-by-step explanation:
Let x = paperback books and y = hardback books
x+y =28
We know that paperbacks cost 1.68 and hardback cost 2.44
1.68x + 2.44y = 54.64
We have 2 equations and 2 unknowns
x+y =28
1.68x + 2.44y = 54.64
