AS A MATH PROBLEM:
\n" ); document.write( "The 12.1 mg amount is contained in a chewable tablet or in a 6-mL volume.\
\n" ); document.write( "a. For tablets
\n" ); document.write( "\"%22=%22\"\"55.54tablets%2F%221+week%22\"
\n" ); document.write( "Rounding would give you \"highlight%2856%29\" tablets in a week,
\n" ); document.write( "and that is what a pharmacist would dispense for a week.
\n" ); document.write( "b. For liquid formulation:
\n" ); document.write( "\"%22=%22\"\"333.2mL%2F%221+week%22\"
\n" ); document.write( "Rounding would give you \"highlight%28333%29\" mL in a week.
\n" ); document.write( "A pharmacist would dispense 350mL if the prescription is for a week,
\n" ); document.write( "so that about 333mL could be taken out of the medicine bottle.\r
\n" ); document.write( "\n" ); document.write( "AS A REAL-LIFE QUESTION:
\n" ); document.write( "a. With 12.1 mg per tablets, 2 tablets would be 24.2mg,
\n" ); document.write( "which is close enough to 24 mg.
\n" ); document.write( "As a mother of a 100-pound child, you would be supposed to give
\n" ); document.write( "2 tablets every 6 hours, meaning \"24hours%2F%226+hours%22=4\" times a day
\n" ); document.write( "That translates to
\n" ); document.write( "\"%282tablets%29%284%29=8\" tablets per day, and
\n" ); document.write( "\"%288tablets%29%287%29=highlight%2856%29\" tablets per week.
\n" ); document.write( "The problem does not look that bad from the point of view of a mother.
\n" ); document.write( "A mother with a 4th-grade education should be competent enough to figure this out,
\n" ); document.write( "and would count to see if there are enough tablets in the medicine bottle for a 1 week vacation.
\n" ); document.write( "If mothers cannot do that, their schooling has failed them.
\n" ); document.write( "b. A measuring teaspoon has a volume of 5mL,
\n" ); document.write( "and the small measuring cups that come with many syrup medications have lines for 5mL, but not for 6mL.
\n" ); document.write( "However, a resourceful mother will figure out what to do.
\n" ); document.write( "A concentration of 12.1mg/6mL means
\n" ); document.write( "\"12.1mg%2F%226+mL%22=%222.0167+mg+%2F+mL%22\"
\n" ); document.write( "In 11mL you would have \"11%282.0167mg%29=22.2mg\", and
\n" ); document.write( "in 12mg there would be \"11%282.0167mg%29=24.2+mg\" ,
\n" ); document.write( "so a mother would give her 100-lb child 12 mL each time,
\n" ); document.write( "measured as accurately as she could manage.
\n" ); document.write( "That would mean
\n" ); document.write( "about \"4%2812mL%29=48mL\" each day, and
\n" ); document.write( "about \"7%2848mL%29=336mL\" each week. \n" ); document.write( "
\n" );
