Answer:

#$50# was the original price.

Explanation:

The best way to approach this type of question is as a direct proportion. You know that #$15# represents #30%# and need to know what value was the #100%#

#$/% = 15/30 = x/100" "larr# cross-multiply

#30x = 15xx100#

#x = (15xx100)/30#

#x = 50#
