Given: f(x) = 2x^2 +5sqrt(x-2)
Evaluate this for x=6:
f(6) = 2(6)^2 + 5sqrt(6-2) = 72 + 5(2) = 72 + 10 = 82 (answer)
X - 3 = 7 (only solution is 10)
2x + 5 = 11 (only solution is 3)
7x - 1 = 27 (only solution is 4)
4x + 2 = -6 (only solution is -2)

When looking at this graph we see 2 things:
(1) How they made the graph, looks awful, anyway...
(2) They practically give you the answer...
When finding an answer to a question like this, you want to use a formula (like this):
A = t * p (where A is the amount of people, t is total amount of people, and p is percent of people / 100)...
So... we fill in the givens...
We know t = 400, and (by looking at the graph) we see that p is around 0.10 and 0.15. So for our sake we'll make p = 0.13 (about halfway)...
A = 400 * 0.13
A ~ 52
The answer is: About 52 people bought 20 items...
And because we got 52, and 52 is close to 54...
<em>The Answer: B.) 54</em>
