Step-by-step reasoning process: Andrea sold 16 x 2 = 32 tickets. Half the number of tickets Jude sold is 16 / 2 = 8. So, Sandra sold 8 + 4 = 12 tickets. Thus, Andrea, Jude, and Sandra sold a total of 32 + 16 + 12 = 60 tickets. Therefore, 100 - 60 = 40 tickets need to be sold.
The question and answer:
Question and answer: There are one hundred tickets to be sold for a volleyball game. Andrea sold twice as many tickets as Jude while Sandra sold 4 more than half the number of tickets Jude sold. If Jude sold 16 tickets, how many tickets need to be sold?
The answer is 40

Step-by-step reasoning process: The second day Richard walks 20 / 2 - 6 = 4 miles. Richard walks 20 + 4 + 10 = 34 total miles. Richard has 70 - 34 = 36 miles further to walk to be in New York City.
The question and answer:
Question and answer: Richard starts walking from Cincinnati to New York City, which is 70 miles. Richards walks 20 miles the first day. The next day he walks 6 miles less than half as much as he walked the first day. He walks 10 miles the third day. How many miles further does Richard have to walk to be in New York City?
The answer is 36

Step-by-step reasoning process: The bulk warehouse has 48 cans for $12.00 so that's 12 / 48 = $0.25 a can. The local grocery store has 12 cans for $6.00 so that's 6 / 12 = $0.50 a can. The grocery store offer is $0.50 a can and the warehouse is $0.25 a can so the grocery store is .50 - .25 = $0.25 more expensive per can.
The question and answer:
Question and answer:
A bulk warehouse is offering 48 cans of sparkling water for $12.00 a case. The local grocery store is offering the same sparkling water for $6.00 and it only has 12 cans. How much more expensive, per can, in cents, is this deal at the grocery store?
The answer is 25
