Question: Mary and Rose went shopping to buy presents. They spent the same amount. Mary bought two pairs of sunglasses for $50 each and a pair of jeans for $100. Rose bought a pair of shoes at $150 and two decks of basketball cards. How much did one deck of basketball cards cost?
Answer: Step-by-step reasoning process: Two pairs of sunglasses costs 2 x $50 = $100. So, Mary spent $100 + $100 = $200. Thus, two decks of basketball cards costs $200 - $150 = $50. Therefore, one deck of basketball cards costs $50 / 2 = $25.
So the answer is 25.

Question: 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?
Answer: Step-by-step reasoning process: 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.
So the answer is 820.

Question: Harry wants to build a homemade helium balloon with his son, Kevin, so he and Kevin go to the store with $200. They buy a giant sheet to turn into a balloon for $42, a rope for $18, and a propane tank and burner for $14. They plan to use the rest of the money on helium. The helium is $1.50 per ounce. For every ounce they buy, the balloon can fly 113 feet higher. How many feet up can they fly the balloon?
Answer: Step-by-step reasoning process: They have $126 for helium because 200 - 42 - 18 - 14 = 126. They can buy 84 ounces of helium because 126 / 1.5 = 84. They can fly 9,492 feet up because 84 x 113 = 9,492.
So the answer is 9492.

Question: Caden has four jars of coins. One jar of pennies, one jar of nickels, one jar of dimes and one jar of quarters. He has twice as many quarters as he does dimes. He has five times as many nickels as he does dimes. He has three times as many pennies as he does nickels. If he has 120 pennies, how much money does he have?
Answer:
Step-by-step reasoning process: Starting with 120 pennies he has $1.20. If he has three times as many pennies as he does nickels, he has 120 pennies / 3 nickels per penny = 40 nickels. 40 nickels = 40 * $0.05 = $2. If he has five times as many nickels as dimes he has 40 nickels / 5 dimes per nickel = 8 dimes. 8 * $0.10 = $0.80. if he has twice as many quarters than he does dimes, he has 8 dimes * 2 quarters per dime = 16 quarters = 16 * $ 0.25 = $4.00. In all he has $1.20 + $2.00 + $0.80 + $4.00 = $8.00.
So the answer is 8.
