September price = S
October price = 1.2S = 1.5/1.2 = $1.25
Money earned in September = 0.4*900*450
Money earned in October = 0.4*700*420
0.30+1.50=1.80
The price was $1.80
b.More in September because they sold more
They earned $360 in September
They earned $280 in October
360-280=80
They earned $80 more in September than October

Answer: The graph will start at (t, v) = (0, 200) decreasing linearly with a slope of -0.2 to the point
(200 - 50) / 0.2 = 750 so the point is (750, 50).
At this point the slope increases to -2 and forward motion stops in an additional
50 / 2 = 25 seconds so the point is (775,0)
distance covered in the first section
vf² = vi² + 2ad
d₁ = (vf² - vi²) / 2a
d₁ = (50² - 200²) / 2(-0.2)
d₁ = 93750 m
distance covered in the second section
d₂ = (0² - 50²) / 2(-2)
d₂ = 625 m
for a total distance of
d = 93750 + 625
d = 94375 m
