Consider the Q and A. Q: At Mario's barbershop haircuts are 50% more expensive during the weekends. If Mario paid $18 for his last haircut on Monday, how much he would have paid the day before?
A: 27
What is the step-by-step reasoning process?
Step-by-step reasoning process: Mario's $18 cut on Monday would have been 50% more expensive on Sunday or $18 * 50% = $9 more expensive. That means he would have paid $9 more on Sunday than what he paid ($18) on Monday or $9 + $18 = $27.

Consider the Q and A. 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: 820
What is the step-by-step reasoning process?
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.

Consider the Q and A. Q: Sandy bought 1 million Safe Moon tokens. She has 4 siblings. She wants to keep half of them to herself and divide the remaining tokens among her siblings. After splitting it up, how many more tokens will she have than any of her siblings?
A: 375000
What is the step-by-step reasoning process?
Step-by-step reasoning process: She will keep 1000000 / 2 = 500000 Safe Moon tokens for herself. For the remaining siblings, they will each receive 500000 / 4 = 125000 tokens. This means that Sandy will have 500000 - 125000 = 375000 tokens more than any of her siblings.

Consider the Q and A. Q: It costs $.10 to print one page. Jenny wants to print 7 copies of her 25-page essay. She also wants to buy 7 pens that each cost $1.50. If she pays the store with 2 twenty dollar bills, how much money should she get in change?
A: 12
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Jenny needs to print 7 * 25 = 175 pages. This will cost 175 * $.10 = $17.5. The pens will cost 7 * $1.50 = $10.50. In total, she will spend $17.5 + $10.5 = $28. Since she pays with 2 twenty dollar bills she pays with 2 * 20 = 40 dollars. Thus, she will get $40 - $28 = $12 in change.
