Question

Raphael paid $664 for camera during a 60% off sale. What was the camera's regular price? I need to see work to understand. Thanks

Answer 1

664=60% off of original

percent means parts out of 100
60%=60/100=0.6

664=60% of original
'of' means multiply
translate

664=0.6 times originail
divide boh sides by 0.6
1106.666666=original
about $1106.67=original
or you could do ratio and proportion
664/60=x/100

answer is still $1106.67
