Jason is a salesperson who sells computers at an electronics store. He
makes a base pay amount each day and then is paid a commission as a
percentage of the total dollar amount the company makes from his
sales that day. The equation P = 100 + 0.03% represents Jason's
total pay on a day on which he sells x dollars worth of computers.
What is the y-intercept of the equation and what is its interpretation in
the context of the problem?
