Answer :
148/x=100/108(148/x)*x=(100/108)*x -148=0.925925925926*x
(0.925925925926) to get x148/0.925925925926=x 159.84=x x=159.84
(0.925925925926) to get x148/0.925925925926=x 159.84=x x=159.84
You would multiply 148x1.08 (when you see a percent, think "out of 100") which equals 159.84. OF always means TIMES. :)
