The easiest/quickest was is this: Type in 1838.65 then x (yes, times button) .93 (point 93) then = button. This is because after minusing 7% from 100 percent you are left with 93%, which gives you the 7% reduction that you wanted. The answer should be 1709.9445 ie 1709.94

Enter 17.5, then press and hold the % 'rate set' button again.

The rate should now be re-set
