Step-by-step explanation:
Let after t hours , the two men are 200 miles apart
So the distance traveled by fthe irst man is 6 miles
And the distance traveled by the second man is 10 miles
So the equation is 6t+10t=200
Therefore after 12.5 hours, they are 200 miles apart.

Answer:
- P(y) = 0.005y² -10y -1000000
- 3,200,000
Step-by-step explanation:
a) Profit is the difference between revenue and cost.
P(y) = R(y) -C(y)
P(y) = (0.005y² +10y) -(20y +1000000) . . . . use the functions for revenue and cost
P(y) = 0.005y² -10y -1000000 . . . . . profit as a function of y
___
b) Evaluating this function for y=30,000, we get ...
P(30000) = 0.005(30000)² -10(30000) -1000000
= 3,200,000
The company will have a profit of 3,200,000 from the sale of 30,000 cars.
