We are given that
Good stuff is giving away pens to each of the first 200 peopel who come in the store today
so, total number of people given is
[tex]N=200[/tex]
In the first hour, they gave 75% of the pens
so, we need to find total number of pens given in first hours
percentage of pens given 1st hour =75%
so,
total number of pens given in first hour = (percentage of pens given 1st hour)*(total number of people given)
now, we can plug values
and we get
total number of pens given in first hour is
[tex]=0.75*N[/tex]
[tex]=0.75*200[/tex]
[tex]=150[/tex]................Answer
