Alright, so Ron parked his car for 8 hours at $3 per hour.
Harry parked his car for 7 hours at $3 per hour.
So, per day Ron is spending (8 * 3) = $24 a day
and Harry is spending ( 7 * 3 ) = $21 a day
So now solve for 5 days. 24 * 5 = $120 21 * 5 = $105
Add both together
$120
+
$105
=
Your Answer:
$225 altogether.

Answer:
he invented the point
he was a German mathematician
he Hilbert's improvements to geometry are still used in textbooks today
he developed Hilbert's axioms
Step-by-step explanation:
The answer would be D. 200 - 20d.
This is because the question asks for pages left after reading for "d" (however many) hours. Since the book has 200 books, you'd subtract from that number since it's the "starting number" of pages. If he reads 20 pages per hour, you would multiply those together to get how many he has read, then subtract that number from 200, to get the amount of pages left.
I hope this helps!
