# $2.50 #

Explanation:

As

#5lbs=$5#

Treating a like basic algebra: dividing both sides by 5:

# (cancel(5) lbs) / cancel(5) = ($cancel(5)) / cancel(5) #

#=> 1 lbs = $1 #

Multiply through by 2.5:

# => 2.5lbs= $1 * 2.50 #

#=> 2.5 lbs = $2.50 #

Or since # 5/2=2.5 # you could half the price to also get the answer
so therefore again...

# 2.5lbs=color(blue)($2.50) #
