Help! Math lovers

Ok my math gurus, I need help. I am not (and never have been) a math lover. I muddled through university stats, got a decent mark on my GRE (for graduate school), and never looked at the stuff again other than simple calculations (which I can generally do just fine). This is giving me a headache though.

Here is a word problem for you:

I went to CherryBerry today and got .18 pounds of froyo (that says point 18, btw; I did not get 18 pounds of froyo- lmao); .15 of that was Pecan Praline (non-fat, no sugar added) which is 80 cals for 4 fl oz./89 g. The rest (basically a dot) was non-fat vanilla (100 calories for 4 fl oz./89 g). I weighed BEFORE toppings (6 mini yogurt chips- the tiny ones) and 1/4 of a teaspoon of colored sprinkles. So. How many calories did I eat (not worried about the toppings, figured about 20 cals there). I eat this at least once a week so I would realllllly like more than an estimate (which I figure to be about 80 calories).
