Answer:

Math textbooks cost $19, while novels cost $8

Explanation:

We can solve this by setting up a system of equations. m will represent the cost of a math textbook, while n will represent novels.

3m+2n=73

2m+4n=70

Multiplying the top equation by 2:

6m+4n=146

Subtracting the second equation from the first:

4m=76

m=$19

n=$8

Hope this helps!
