Simple interest, I = 101.40
Time, t = 6 years
interest, i = 1.3%
Interest, I=Pit, rearrange
Principal, P=I/(it)=101.40/(6*0.013)=1300
6x² + 11x - 35 = (3x - 5)(2x + 7)
=> (3x - 5)(2x + 7)/(3x - 5)
i.e. 2x + 7...........as the 3x - 5 term cancels.
50% of 40 is 20.
40/2 =50.
Just divide the number by 2 anytime it asks for 50%.
