Question
Bella spent 4/7 of her money on a dictionary and 3 identical books. She spent 1/6 of the remainder on a journal that cost $7. How much did she spend on the dictionary and 3 books?
If 3/8 of the cost of the dictionary was the same as 1/2 of the total cost of 3 books, how much did each book cost?
I've got $56 on the first question, but I'm having a hard time trying to solve the second one. Any help, please?

$7 is 1/6 of 3/7 of Bella's money, so she had $98 to start with. 4/7 of 98 is $56, as you figured.
The dictionary and the books cost 56
d+3b = 56
3/8 d = 1/2 * 3b
so, 3d = 12b
4b + 3b = 56
b = 8
check:
3 books cost 24
dictionary cost 32
3/8(32) = 1/2(24)
12=12
The dictionary and the books cost 56
d+3b = 56
3/8 d = 1/2 * 3b
so, 3d = 12b
4b + 3b = 56
b = 8
check:
3 books cost 24
dictionary cost 32
3/8(32) = 1/2(24)
12=12
