Answer:

6

Explanation:

Set up a ratio

The percentage of candy bars left is # 100 - 70 =30#

Let 30% be the partial percentage.
Let 100% be the total percentage.
Let x be the partial number of candy bars.
Let 20 be the total number of candy bars.

# 30/100 = x/20# Multiply both sides by 20

# (30 xx 20)/100 = ( x xx 20)/20# This leaves

# 600/100 = x # Dividing by 100 gives

# 6 = x #
.
There are 6 candy bars left
