#42.35#

Explanation:

When adding decimals you can add them in steps. In this case you can first add the 10's,

#10 + 20 = 30.00#

Then the 1's,

#5+6 = 11.00#

Then the .1's can be added also known as the one/tenths or the #1/10#'s,

#9/10 + 3/10 = 12/10 = 1 2/10 = 1.20#

Then the .01's can be added also known as the one/hundredths or the 1/100's,

#8/100 + 7/100 = 15/100 = 1/10 + 5/100 = .10 + .05 = 0.15#

Now we can add all the numbers together,

#30.00 + 11.00 + 1.20+0.15 = 41.00 + 1.20 + 0.15 = 42.20 + 0.15 = 42.35#
