Final answer:

Kathy worked 17 hours at Job A and 13 hours at Job B to make a total of $193.90.

Step-by-step explanation:

To solve this problem, let's assume Kathy worked x hours at Job A and (30-x) hours at Job B. We can set up an equation to represent the total earnings:

5.90x + 7.20(30-x) = 193.90

Solving this equation, we find that:

5.90x + 216 - 7.20x = 193.90

-1.30x = -22.10

x = 17

Therefore, Kathy worked 17 hours at Job A and 13 hours at Job B to make a total of $193.90.
