In one day, a book store earned $185 in sales for 4 copies of a new cookbook and 5 copies of a new science fiction novel. On the next day, it earned $142 in sales for 3 copies of the cookbook and 4 copies of the science fiction novel. What was the price of each book?

Step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512
