The answer to your question is D. I hope that this is the answer that you were looking for and it has helped you.
It’s one 2/3’s in 1 whole
A good way to set up percentage problems is by using "Part = Percent × Whole".
In this case, our part is 140, our percent is 80 (because that 20% wa s took of from the original 100%), and our whole is unknown. If we fill in the equation we get this:
140=80×x.
if we solve the equation by dividing both sides by 80, we get $1.75=x. Because we replaced 80% with 80,we have to divide by 100 since we multiplied by 100 in the beginning. So, we get that $175 was the original price.
At time 0, there are 16 gallons of water.
That gives you point (0, 16).
This point is a dot on 16 on the y-axis.
After 1 hour, the water went sown 2 gallon.
At hour 1, there are now 14 gallons left.
This gives you point (1, 14).
To plot it, start at the origin, (0, 0), go 1 unit right on the x-axis, and 14 units up om the y-axis, and place a dot there.
Now connect the two dots and extend the line down to the right until you intersect the x-axis. You should intersect the x-axis at 8.
