Answer:

More than 6.8 yards per game.
Step-by-step explanation:
Let x be the possible number of yards per play for the winning team.
We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.
We have been given that a winning football team more than doubled the offensive yards gained by its opponent.
We can represents this information in an inequality as:

Therefore, the inequality
can be used to find the possible number of x of yards per play for the winning team.
Let us solve for x.

Let us divide both sides of our inequality by 80.


Therefore, the winning team will score more than 6.8 yards per play.
Given number is 4,8100,000,000,000.
In this number of zero is 11. So we can write it as

But for scientific notation we will enter decimal after two place in reverse direction.For this we will also multiply number by 10^2.
So number will be

So fourth option is correct.
