Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Range which must be hauled by trucks :

150,000 - 180,000 yds of earth

Haul per day = 10000 yds

Already removed = 120,500

We can express the problem as an inequality:

Using y = number of days

150,000 ≤ (10000y + 120,500) ≤ 180000

150,000 ≤ (10000y + 120,500)

150000 - 120500 ≤ 10000y

29500/10000

y = 2.95 days

10000y + 120,500 ≤ 160000

10000y ≤ 160000 - 120500

y = 39500/10000

y = 3.95

2.95 ≤ y ≤ 3.95
