Question: Katrina has 120 cookies to sell at her bakery. She plans to take home any cookies she doesn’t sell by the end of the day. In the morning, she sells 3 dozen cookies. During the lunch rush, she sells 57 cookies. In the afternoon, she sells 16 more cookies. How many cookies does she have left to take home?
Answer: Step-by-step reasoning process: There are 12 cookies in 1 dozen, so in the morning, she sold 12 x 3 dozen = 36 cookies. Throughout the day, she sold 36 cookies in the morning + 57 cookies at lunch + 16 cookies in the afternoon = 109 cookies. She started with 120 cookies – 109 cookies sold = 11 cookies to take home.
So the answer is 11.

Question: Mark and James need a total of 14 dice that are 12 sided to play their game. Mark has a bag of 10 dice and 60% of them are 12 sided. James has a bag of 8 dice and 75% of them are 12 sided. How many dice will the boys need to buy to play their game?
Answer: Step-by-step reasoning process: Mark has 60% 12 sided dice, so 60 / 100 * 10 dice in his bag = 6 12 sided dice. James has 75% 12 sided dice, so 75 / 100 * 8 dice in his bag = 6 12 sided dice. They will need to purchase 14 dice - 6 dice - 6 dice = 2 dice.
So the answer is 2.

Question: Jack has been driving for the past 9 years. He drives 37,000 miles every four months. How many miles has Jack driven since he started driving?
Answer: Step-by-step reasoning process: There are 12 / 4 = 3 four month groups in a year. Jack drives 37,000 * 3 = 111,000 miles in a year. Jack has driven 111,000 * 9 = 999,000 miles since he has started driving.
So the answer is 999000.

Question: Oliver has 10 $20 and 3 $5 bills. William has 15 $10 and 4 $5 bills. How much more money does Oliver have than William?
Answer:
Step-by-step reasoning process: Oliver's $20 bills amount to $20 x 10 = $200. Oliver's $5 bills amount to $5 x 3 = $15. So, Oliver has a total of $200 + $15 = $215. William's $10 bills amount to $10 x 15 = $150. William's $5 bills amount to $5 x 4 = $20. So, William has a total of $150 + $20 = $170. Therefore, Oliver has $215 - $170 = $45 more than William.
So the answer is 45.
