Answer:
50/1, 100/2, 250/5, 400/8
<h3>
Answer: 450 mph</h3>
========================================================
Explanation:
a = speed of airplane without any wind
a+50 = speed of the plane with the wind boosting it
distance = rate*time
d = r*t
d = (a+50)*4
This represents the plane traveling 4 hours at the speed of a+50 mph. We don't really care about the distance d.
The other equation to set up is
d = (a-50)*5
which means the plane is going slower at a-50 mph and travels for 5 hours this time.
The system of equations is
Both equations involve the same variables 'a' and d, which allows us to use substitution to solve for 'a' like so
d = (a+50)*4
(a-50)*5 = (a+50)*4
5a-250 = 4a+200
5a-4a = 200+250
a = 450
The speed of the plane, without any wind, is 450 mph

Answer: Disposable income = $100.
Explanation:
Since we have given that
And, average propensity to consume = 1
i.e. APC = 1
As we know the formula of APC ,
So, our equation becomes,
Hence, Disposable income = $100.
