Raphael paid $ 160$160 for a camera during a 75 %75% off sale. What was the camera's regular price?

So paid160

75 percent off

100 percent=original

75 percent off=100-75=25%

160=25% of original cost

'of' means multiply

remember tha tpercent is parts out of 100 so

25%=25/100=1/4

160=1/4 times original cost

multily both sides by 4

640=original cost

answe ris $640 = original cost
