Simple physiological model

According to a simple physiological model, an athletic adult male needs 20 calories per day per pound of body weight to maintain his weight. If he consumes more or fewer calories than those required to maintain his weight, his weight changes at a rate proportional to the difference between the number of calories consumed and the number needed to maintain his current weight; the constant of proportionality is pounds per calorie. Suppose that a particular person has a constant caloric intake of calories per day. Let be the person’s weight in pounds at time (measured in days).

(a) What differential equation has solution ?

(Your answer may involve W, H and values given in the problem.)

(b) Solve this differential equation, if the person starts out weighing 175 pounds and consumes 3300 calories a day.

(c) What happens to the person’s weight as ?

Assorted expenses that are involved in preparing for higher education

An Amazon warehouse worker makes about $32,000 a year. Jeff Bezos could have given each Amazon
worker an additional $105,000 and still be as rich as before the pandemic. If you were to add this profit per
employee to existing salary, it would amount to $137,000. Imagine you are supporting a family of 4 (2 adults
and 2 children) on the pay of one Amazon warehouse worker. Thinking back to Part 1, what experiences for
your children would you be able to afford with the actual pay of an Amazon warehouse worker ($32,000 a year
or $2667 a month) vs. the amount with profits distributed ($137,000 a year or $11,416 a month)? Remember
that you must take care of your family’s basic necessities (food, child care, housing, medical, transportation,
etc.) and pay taxes before you spend money on preparing your children for college. (Hint: You can use the
living wage calculator for an estimate.) How does this relate to both exploitation and opportunity hoarding? You
should cite relevant course materials from this week and/or past weeks in your answer using ASA-style
citations with page numbers.
