Trucks must haul between 150,000 yd' and 180,000 yd of earth each day to create a new water park near Universal Studios in Orlando, Florida. The trucks can haul 10.000 yd per day

and 120,500 yds have already been brought to the site. How many days are needed to

complete this job?

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
