Answer the following question.
If Janet reads 80 pages a day and Belinda reads 30 pages a day, how many more pages does Janet read in 6 weeks?
Step-by-step reasoning process: First find the total number of days in 6 weeks: 6 weeks * 7 days / week = 42 days. Then find the total difference in the number of pages Janet and Belinda read each day: 80 pages / day - 30 pages / day = 50 pages / day. Then multiply the daily difference by the number of days to find the total difference in the number of pages they read: 50 pages / day * 42 days = 2100 pages.
The answer is 2100.

Answer the following question.
John decides to learn how to play the piano. He buys a piano for $500. He then hires a teacher for 20 lessons at $40 per lesson but ends up getting a 25% discount. How much did everything cost?
Step-by-step reasoning process: The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100.
The answer is 1100.

Answer the following question.
A doctor needs to give medicine to a child, and he knows that he cannot give the same amount of medicine that he would give to an adult. The instructions say that for every kilogram of weight the child must be given 5 ml of medicine. The doctor knows that the child weighs 30 kilograms and that also the full dose has to be given in 3 equal parts. How many milligrams will each part of the dose be?
Step-by-step reasoning process: The total number of ml needed is 30 kg x 5 ml / kg = 150 ml. Each dose has to be 150 ml / 3 doses = 50 ml / dose.
The answer is 50.

Answer the following question.
Jordan picked 54 mangoes from his tree. One-third of the mangoes were ripe while the other two-thirds were not yet ripe. Jordan kept 16 unripe mangoes and gave the remainder to his sister who pickled them in glass jars. If it takes 4 mangoes to fill a jar, how many jars of pickled mangoes can Jordan's sister make?
Step-by-step reasoning process: Jordan picked 54 / 3 = 18 ripe mangoes. He picked 54 - 18 = 36 unripe mangoes. Jordan gave 36 - 16 = 20 unripe mangoes to his sister. Jordan's sister can make 20 / 4 = 5 jars of pickled mangoes.
The answer is 5.
