It's asking "what are the set of y coordinate values for all of the points on the red line?"
In this case, all of the points on this red line have a y coordinate of y = 6. Two such points on this red line are (0,6) and (1,6)
So that's why the only answer is choice D) 6. This is the only number in the range. The range is the set { 6 }. No other number is in the range, so no other choice A, B, C, E, F are true
-----------------------------------------------------------------
Answer: Choice D) 6
(note: none of the other boxes are checked off)
Answer:
Step-by-step explanation:
Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...
12%·x +6%·(5900 -x) = 540
0.06x + 354 = 540 . . . . . . . . eliminate parentheses
0.06x = 186 . . . . . . . . . . . . . . subtract 354
x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06
Scott invested $3100 at 12% and $2800 at 6%.

<em>Quick sanity check</em>
The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.
