Each note book was $2, since he was buying 6 note books and he had 12 dollars left over you can assume he spent 12 dollars and 6*2=12 so we know he spent 2 dollars on each individual book :)
Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
