The park is 1 ½ miles from your house. The mall is 2 ¼ miles from your house:
a. Find the minimum distance between the park and the mall.
b. Find the maximum distance between the park and the mall.
c. Write and inequality that describes the possible distances d between the park and the mall.
No two sides when added together can be shorter than the 3rd side.
No one side can be longer than the other two sides added together.
x < s1 and s2 long side < x + short side
long side < other two sides, and x < other two sides47. 7 ½ < x + 3 ¼ and x < 3 ¼ + 7 ½
4 ¼ < x and x < 10 ¾
4 ¼ < x < 10 ¾

Total income of 100 people = average income x 100
=$74,750 x 100
=$7,475,000
Total income of 99 people =$7,475,000-$5,000,000 = $2,475,000
Mean of 99 people = $2,475,000 = $25,000
