Question: Jack and Jill race up the hill to see who gets there fastest. Jack ran up the first half of the hill in 19 seconds. He finished running up the hill 7 seconds before Jill did. If Jill finished the race in 32 seconds, how long did it take Jack to run up the second half of the hill?
Answer with step-by-step thinking: Since Jack was faster than Jill, his total running time must have been 32 - 7 = 25 seconds. Subtracting the the time he spent running up the first half of the hill shows that it took 25 - 19 = 6 seconds to run up the second half of the hill.
So the answer is 6.


Question: Ben has $2000 for his business operations costs. He orders goods from his supplier and writes them a cheque for $600. His debtor pays him $800 from the purchases they had made on credit. Mr. Ben then decides to do equipment maintenance and spends $1200 on the whole operation. How much money is Mr. Ben remaining with?
Answer with step-by-step thinking: When Mr. Ben writes the cheque, he remains with $2000 - $600 = $1400. His debtor pays him $800, increasing his operation capital to $1400 + $800 = $2200. He spends $1200, remaining $2200 - $1200 = $1000 for business operations cost after maintenance.
So the answer is 1000.


Question: Randy has some money in his piggy bank. He spends 2 dollars every time he goes to the store. He makes 4 trips to the store every month. If he had $104 dollars left in his piggy bank after a year, how much money, in dollars, did he have at first?
Answer with step-by-step thinking:
Randy spends 2 * 4 = 8 dollars every month. Randy spends 8 * 12 = 96 dollars in a year. Randy had 96 + 104 = 200 dollars in his piggy bank at first.
So the answer is 200.
