Since the cost of one extension cord is unknown, let us assume it to be a certain number #x#.

Six extension cords cost $7.26. We can write this as:

Cost of one cord × 6 = $7.26

That is,

#x# × #6=7.26#
#6x=7.26#

#x=7.26/6#

#x=1.21#

Therefore, we can conclude that one extension cord costs $1.21.


I think it's useful to remember that if you're given the cost of a certain number of things, you can find out the cost of one of those things by dividing by the number of total number of things.

Say, #n# number of items cost some amount.

Then, one item would cost

Total cost of #n# items#/n#
