Ashley has a lot of friends she gave lollipops too, #18# friends to be exact.

Explanation:

The formula for this problem can be written as:

#40 - 2f = 4# Where #40# is the number of lollipops Ashley originally had; #f# is the number of friends Ashley gave #2# lollipops each to and #4# is the number of lollipops remaining.

Solving for #f# while keeping the equation balanced gives the solution:

#40 - 2f - 40 = 4 - 40#

#0 - 2f = -36#

#-2f = -36#

#(-2f)/-2 = (-36)/-2#

#1f = 18#

#f = 18#
