#$80#

Explanation:

A drop of 20 % means find 80% = #xx 0.8#
An increase of 10% means find 110% = #xx 1.1#

Let the original price be #x#. We can follow what was done to this price in the form of an equation.

Decreased by 20% then raised by 10%..

#x xx0.8 xx1.1 = 70.40" "# Now just solve for #x#

#x = 70.40/(0.8 xx1.1#

=#$80#
