d.
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so

b. If
draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so 
c. Note that
then

d. Coordinates of point L are (c,t), coordinates of point K are (a,p)
Answer:
70 increased by 6 percent = 74.2
Step-by-step explanation:
I think the answer is $560
working:
$875 * 64% = $560
8,869 + 3,742 = 12,411. Rounded it's C., 12,400. Hope that helps!
The two angles form a straight line and need to equal 180 degrees
180 - 61 = 119
The missing angle is 119 degrees
