The answer is 10.8. You turn 10 4/5 into 54/5. Then you divide 54 by 5.
Given that the two angles form a linear pair, let second angle be x, the first angle will be 3x because it is 3 times the second angle. But linear angles add up to 180, thus
x+3x=180
4x=180
hence
x=180/4
x=45°
thus the measure of the first angle will be :
3x=3*45=135°
the second angle is 45°
$3.60
You can get this by determining that the rate of which they are paid is $4 an hour (divide the total by the amount of hours). Then you can find the rate of which they collect dues by dividing the amount they paid by their total (3%).
Using those numbers you can find the total amount the second person paid.
