Using proportions, the amounts of medicine that can be taken are given as follows:
a. 72 pills.
b. 2 cold pills.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, we have that one painkiller pill has 450 mg, and the recommended maximum daily dosage is of 3250 mg, hence the maximum number of pills is:
3250/45 = 72 pills. (rounded down, as rounding up would result in a higher dosage).
For item b, the dosage of painkillers is:
450 x 5 = 2250 mg.
1000 mg, as 3250 - 2250 = 1000, can be used for the cold pills, hence the maximum number of cold pills is:
1000/350 = 2 cold pills.
