She walks 3 mph because when you divide it by 2 it will equal
3 miles in 1 hour
Two equations are given
b+t <=9
30b + 20t > 200
WE graph each inequality
b + t <= 9
Make a table for b + t < = 9
b --- > t
0 --> 9
2 --> 7
Plot the point and make a graph. WE shade the bottom region because we have <= symbol
The graph is attached below.
WE graph the inequality
30b + 20t > 200
Make a table for 30b + 20t > 200
b --- > t
0 --> 10
6 --> 1
Plot the point and make a graph. WE shade the upper region because we have > symbol
The intersection of shaded region is our solution.

45
Answer:
f(n) = n/36
Step-by-step explanation:
The length of a string is given in yards, is a function f(n) of the length n in inches.
We have to write a function rule for this situation.
∵ 36 inches = 1 yard
∴ 1 inch = 1/36 (yard)
∴ n inches = n/36
and function representing the length will be
f(n) = n/36
