Answer:
Whoa, that's a lot to answer...
15. 30000=500x
16. y=58x+5
in 16, the total cost is y, so y has to be in 1 side for itself. and we need to add the amount of tickets and the fee (5$). So we get that equation.
We are trying to find miles/hour, which shows that we are going to be dividing the total number of miles by the total number of hours. Thus, in this case, the miles/hour rate will be:

He drove 40 miles in one hour.
S= 70w + 750
s(19) = 70w x 19+350= 1680
so its 1680
I don't think anyone can solve this without seeing the table mentioned in the question :)
It’s 20 % hope that helps!
