The price of a ring is decreased by 40% and the resulting price is increased by 50%. The final price is $360. What was the original price?

I've tried this problem a few times, but I haven't gotten any good answers yet.

Again, thanks so much! I appreciate your help!

**Reiny**, Thursday, November 6, 2008 at 9:18pmlet the original price be $x

so after the first reduction of 40%, the new price is .6x

now this is cut in half (50%)

so the new price is .3x

.3x = 360

x = 360/.3

= 1200

so the original price was $1200

check: 40% of 1200 = 480 leaving 720

now 50% of 720 = 360
