She paid for the computers using two different financing plans. For the desktop the interest rate was 6% per year, and for the laptop it was 7% per year.

The laptop costs $300 less than the desktop, so...
let x = cost of laptop
then x+300 = cost of desktop
The total finance charge of $252 is from 7% of the cost of the laptop and 6% of the cost of the desktop:
The cost of the laptop is x = $1800;
the cost of the desktop is x+300 = $2100.
