k, number which Kayla sells
2k-5, number which Austin sells


I am assuming you said,"cost" when you meant to say "price" of their magazines.
Austin's revenue, 18.2%282k-5%29
Kayla's revenue, 32.5k

Total revenue both combined, 18%282k-5%29%2B32.5k=951.2;

The question would seem to be asking for the value of k%2B%282k-5%29=3k-5.
