Answer:
Step-by-step explanation:
Think of of this as a function in which the number of pounds is a function of the number of hours. Each piece of given information is a point. Each point has the format (x, y) = (hours, pounds), where hours is x and is the independent variable, and pounds is y and is the dependent variable. 
You have two points (4.5, 1445) and (7, 2320). First find the slope of the line that passes through those two points. Use the slope formula, 
m = (y2 - y1)/(x2 - x1). 
Then using the slope and the point-slope equation of a line, find the equation of the line. The point-slope equation of a line is 
y - y1 = m(x - x1), 
where m = slope, and the point is (x1, y1).

Answer: the percent of study group students from outside the state is 13%
Step-by-step explanation:
The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%
The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.
Since the rest are from outside the state, the percent of study group students from outside the state would be 
100 - (80 + 7) = 100 - 87 = 13%
