Answer the following question.
Today is my birthday and I'm three times older than I was six years ago. What is my age?
Step-by-step reasoning process: We know that my age divided by three is equal to my age minus six therefore X / 3 = X - 6 where X = My age. This means that X = 3X - 18 because we can multiply both sides by 3. This also means that - 2X = - 18 because we can subtract 3X from the right side. Therefore X = 9 because - 18 / - 2 = 9.
The answer is 9.

Answer the following question.
Noah, who loves his Grammy, calls her every week to talk about his day. If each call lasts 30 minutes and he is charged $0.05 per call minute, how much would he be billed if he makes the calls for a year?
Step-by-step reasoning process: A year has 52 weeks, so if he talks for 30 minutes every week, the total number of call hours is 52 * 30 = 1560 minutes. Since he is charged 0.05 cents per call, the total cost is 1560 * .05 = 78 dollars.
The answer is 78.

Answer the following question.
The world record for longest fingernails is 26 inches. Sandy, who just turned 12 this month, has a goal for tying the record. Her fingernails are 2 inches long. Her fingernails grow at a rate of one-tenth of an inch per month. How old will she be when she achieves the world record?
Step-by-step reasoning process: Sandy's fingernails will grow a total of ( 0.1 ) * 12 = 1.2 inches per year. To achieve the world record, Sandy needs to grow her fingernails a total of 26 - 2 = 24 inches. It will take her a total of 24 / 1.2 = 20 years. Sandy will be 12 + 20 = 32 years old when she achieves the world record.
The answer is 32.

Answer the following question.
Andy is running late. School starts at 8:00 AM and it normally takes him 30 minutes to get there, but today he had to stop for 3 minutes each at 4 red lights and wait 10 minutes to get past construction. If he left his house at 7:15, how many minutes late will he be?
Step-by-step reasoning process: First find how many minute Andy had to get to school when he left his house: 8:00 AM - 7:15 AM = 45 minutes. Then find the total time he spent waiting at red lights: 3 minutes / light * 4 lights = 12 minutes. Now add the normal travel time, red light time, and construction wait time to find Andy's total travel time: 30 minutes + 12 minutes + 10 minutes = 52 minutes. Now subtract the amount of time Andy had when he left his house from that number to find how many minute late he is: 52 minutes - 45 minutes = 7 minutes.
The answer is 7.
