Amine extracts 2 tons of ore in an hour. of the total ore extracted in a day, 4 tons is purchased by the government and more than 10 tons is sold to a mineral extractor. if the mine operates for x hours in a day, what is the simplest inequality that represents the number of hours the mine must operate to meet its obligations?
a.
x > 3
b.
x > 4
c.
x > 5
d.
x > 7

Step-by-step explanation:

So you know that you are producing two tons of ore an hour. Since the government is buying four tons a day and a mineral extractor is buying more than ten tons a day you would need over 14 tons over ore a day. Since you are extracting 2 tons in one hour it will take at least seven hours to get a bare minimum. But since the mineral extractor is buying upwards of ten tons you would have to work longer so your answer would be D. X>7

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
