Answer:

8 books

Step-by-step explanation:

set up a system of equations:

b+m=12

16+12b=112

*let b represent books, let m represent magazines

we can automatically solve the second equation to find out how many books she bought since we know that she spent $16 on magazines

16+12b=112

12b=96

b=8

so, she bought 8 books
