Percentage P6

If Larry sells his toy at a discount of 20%, he can still make a gain of $150. If he sells it at a 45% discount, he will lose $325. How much did Larry pay for his toy?


80%  -->  1 u  +  $150

55%  -->  1 u  -  $325

80%  -  55%  -->  150  -  (- 325)

25%  -->  150  +  325  =  $475

80%  -->  80/25  x  475  =   $1520

1520 -  150  =  $1370

It was $1370.
