#79.2 " grams"#

Original dose is 65 gm.

increase is 20% so:

#66 " grams" * 20%# or #66 " grams" *0.2 = 13.2 " grams"#

so the new dose will be the original dose + the increase:

#66 " grams" + 13.2 " grams" = 79.2 " grams"#

Don't forget a correct answer for any word problem requires units.

#78g# of medication.

This method is quicker than the one where you find the #20%# and add it on.

An increase of #20%# means #100%+20% = 120%#

Now find #120%# of #65g#

#120/100 xx 65#

#=78g#

Note the method without resorting to a calculator:

#cancel120^6/cancel100_cancel5 xx cancel65^13#

#6xx13 =78#
