Q: Mark was caught speeding and the judge wants to make an example out of him. The base fine for speeding is $50 but additional penalties apply in this case. The fine is increased by $2 for every mile per hour Mark was going over the speed limit. He was going 75 miles per hour in a 30 mile per hour zone. The fine is also doubled because he was in a school zone. Finally, the judge makes Mark pay $300 in court costs and he also has to pay his lawyer $80/hour for three hours of work. How much does Mark owe for this speeding ticket?
A: First figure out how many miles over the speed limit Mark was going: 75 mph - 30 mph = 45 mph. Now figure out how much the per - mile fine is: $2 / mph * 45 mph = $90. Now add that amount to the base fine: $90 + $50 = $140. Now double that amount for being in a school zone: $140 * 2 = $280. Now figure out how much Mark owes his lawyer: $80 / hour * 3 hours = $240. Now add the court costs, lawyer fees and fine: $240 + $300 + $280 = $820. The answer is 820.

A: They have played 30 total games because 12 + 18 = 30. The proportion won by Archibald is .4 because 12 / 30 = .4. The percentage he has won in 40% because .4 x 100% = 40%. The answer is 40.

Q: It cost 50 dollars to get cats ready for adoption, 100 dollars to get adult dogs ready for adoption, and 150 to get puppies ready for adoption. If 2 cats, 3 adult dogs, and 2 puppies are adopted what was the cost to get them ready?
A:
The cost to get the cats ready is 2 * 50 = $100. The cost to get adult dogs ready is 3 * 100 = $300. The cost to get puppies ready is 2 * 150 = $300. The total cost is 300 + 300 + 100 = $700. The answer is 700.
