In an equation system you'll have:

- System with more questions than equations: infinite solutions
- System with the same number of questions as equations: only one solution with as many answers as questions
- System with two or more independent and <span>contradictory equations: zero solutions.

In this case you have two independent equations and two questions (x and y), so the answer is d, one solution.</span>

The interest rate on her account would be 38.4%.

If we use the simple interest formula I=PrT, the principle (P) would be 6000. Assuming that it is based on annual interest, the time (t) would be 1/12. Then, you multiply 6000 by 1/12 to get 500. Finally you divide 192/500 and then multiply by 100.


If the time is based on monthly payments, then do the same thing, except multiply 6000 by 1
