D = rt
D = 50(4)
D = 200 miles
From a coordinate point of view, we have a function D(x) = 50x, where x represents time in hours.
When x = 4, y = 200.
(x, y) = (domain, range).
Our domain is 4 hours and range 200 miles.

Answer:
D
Step-by-step explanation:
Since the order does not matter, then it is a combination question,
So you just use the combination technique,
10C3 = 10!/(10!(10-3)!) = 120 ways

Answer: $18</h3>
========================================================
Work Shown:
40% = 40/100 = 0.40
40% of 45 = 0.40*45 = 18
The sale price is $18. You save 45-18 = 27 dollars.
Note how 27/45 = 0.60 = 60%, meaning you got a 60% discount. Furthermore, note how 60% + 40% = 100%. So if you get a 60% discount, you still have to pay 40% of the original price.
