Answer: So for the 9.5% percent I'm not sure if you mean by 9.5% off the price or more for the price so Ill just do both
If you subtract $300 from 9.5% you get 271.5 US$
But if you add $300 to 9.5% you get 328.5 US$
1,503 + 847 + 4,219 = 6,569
132 x 14.1% = 18.612
So 18.612 rounded to 18.6
Same as before
total=(2w+75)(2w+35)=4w²+220w+2625
pool=75 times 35=2625
minus pool from total
4w²+220w+2625-2625=4w²+220w
Direct variation has this equation:
y = kx
where k is the constant of variation
y = -5 ; x = -15
y = kx
-5 = k(-15)
-5/-15 = k
1/3 = k
Choice D. y = 1/3 x
