6. Today’s Objective
To be able to use a linear inequality in a real-life situation.

7. Example 1
In order to get a B or higher in this class, you must get a score higher than 79.4%. Write an inequality that describes getting a B or higher.
S > 79.4

8. Example 2
Sue and Bob ran a 2 mile race. Bob finished ahead of Sue, and Sue’s time was 8 minutes.
Write an inequality that describes Bob’s average speed for the race.

9. Example 2 Speed = distance time Bob’s avg. speed = B
Sue’s distance = 2
Sue’s time = 8
B > 2/8 or 1/4
Bob’s speed was greater than 1/4 mile per min.

10. Example 3
For the circumference of a circle to be at least 22, what can the radius r be? r
C = 2r

11. Example 3
2r = c
2r > 22
2r/2 > 22/2
r > 11
