If a caterer offers a package that feeds up to 50 people for $1,500, the amount of packaged that fed one person will be $1500/50 which is $30.
If there is an additional charge of $24.75 on each person, the total amount spent on each person will be $50+$24.75 which is $74.75.
The linear model that represent total amount charge per host s as a function of additional guest will be $30s+g since a person spent $30 plus additional charge of 'g'
