Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.
The selling price would be $11.20.
40% = 40/100 = 0.4
The mark up is 40% of the cost; this means 40% of 8:
40% of 8 = 0.4(8) = 3.20
8 + 3.20 = 11.20
I believe the answer is D
y+2=-2(x-5)
-2*-5=10
y+2=-2x+10
-2 -2
y=-2x+8
