Consider the Q and A. Q: Rene has three times as many dolls as her sister, while her sister has two more dolls than their grandmother. If their grandmother has 50 dolls, how many dolls do they have altogether?
A: 258
What is the step-by-step reasoning process?
Step-by-step reasoning process: If the grandmother has 50 dolls, Rene's sister, who has 2 more dolls than their grandmother, has 50 + 2 = 52 dolls. Together, Rene's sister and the grandmother have 52 + 50 = 102 dolls. Since Rene has three times as many dolls as her sister, she has 52 * 3 = 156 dolls. Altogether, they have 156 + 102 = 258 dolls.

Consider the Q and A. Q: Bob buys 50 feet of rope. He uses a 5th of it to make a small piece of art. He takes the rest and gives half of it to the friend. After that, he cuts 2-foot sections. How many sections does he get?
A: 10
What is the step-by-step reasoning process?
Step-by-step reasoning process: He cuts off 50 / 5 = 10 feet. So he has 50 - 10 = 40 feet left. He gives half away which means he has 40 / 2 = 20 feet. So he has 20 / 2 = 10 sections.

Consider the Q and A. Q: Samson is going to another town which is 140 km away. He will use his car that uses ten liters of gasoline for a distance of 70 km. How many liters of gasoline will Samson need for a one-way trip?
A: 20
What is the step-by-step reasoning process?
Step-by-step reasoning process: Samson will need 140 km / 70 km = 2 ten liters of gasoline for a one - way trip to a town. Therefore, he will need a total of 2 x 10 liters = 20 liters of gasoline.

Consider the Q and A. Q: Every hour past noon shadows from a building stretch an extra 5 feet, starting at zero at noon. How long are the shadows from the building 6 hours past noon in inches?
A: 360
What is the step-by-step reasoning process?
Step-by-step reasoning process:
If the shadows lengthen by 5 feet per hour, this means that in 6 hours the shadows would have lengthened from zero to 5 * 6 = 30 feet. Since there are 12 inches in every foot, this means the building's shadow would be 30 * 12 = 360 inches in length.
