a scientist had a bottle that contained 56.6 mL of a solution. She used 3.2 mL of a solution for an experiment. Then she poured half the solution remaining in the bottle into a beaker. Finally she poured 6 mL of the solution remaining in the bottle into a test tube. How many milliliters of solution remained in a bottle?
+130511 56.6 - 3.2 = 53.4 ml
(1/2) 53.4 = 26.7 ml
26.7 - 6 = 20.7 ml remained in the bottle
