Combined weigh #= 1.56# kg.

Let each box of cookies be #x#.

Each box (#x#) weighs 520 grams :

#x=520# g

The question asks us to give an answer in kilograms. Change grams to kilograms by dividing #x# by #1000# (since #1000# g #= 1# kg).

#x=0.52# kg.

Now that we have an expression for #x#, we can multiply both sides by #3# to find the total weight of all #3# boxes of cookies.

#3x=3*0.52#
#3x=1.56# kg

Hope this helps :)
