To determine how many times faster Carl Lewis is than a honeybee, we can divide the honeybee's time by Carl Lewis' time:

20.706 seconds ÷ 9.86 seconds = 2.1

Therefore, Carl Lewis is approximately 2.1 times faster than a honeybee.

To find Grammy's price per ounce for cider, we need to divide the total price by the total number of ounces:

Grammy's price per ounce = $2.09 ÷ 34.7 ounces = $0.06 per ounce

To use the five-step thinking plan to solve this problem:

Step 1: Understand the problem
- Jill has $8.75.
- Jack has three times as much as Jill.
- Jack spent $5.00 on a book.
- We need to find out how much money Jack has.

Step 2: Make a plan
- We'll first calculate three times Jill's amount.
- Then, we'll subtract the $5.00 that Jack spent.

Step 3: Solve the problem
- Jill's amount: $8.75
- Jack's amount (3 times Jill's amount): 3 * $8.75 = $26.25
- Jack's amount after buying the book: $26.25 - $5.00 = $21.25

Step 4: Check the solution
- The solution seems reasonable; Jack does have more money than Jill.

Step 5: Communicate the solution
- Jack has $21.25.

Therefore, Jack has $21.25.

To use the five-step thinking plan to solve this problem:

Step 1: Understand the problem
- Karenna solved the math problem in 7.9 minutes.
- Chase took 2.3 times longer to solve the same problem.
- We need to find out how long Chase took to solve the problem.

Step 2: Make a plan
- We'll first calculate 2.3 times Karenna's time.
- Then, we'll adjust the units if necessary.

Step 3: Solve the problem
- Karenna's time: 7.9 minutes
- Chase's time (2.3 times Karenna's time): 2.3 * 7.9 = 18.17 minutes

Step 4: Check the solution
- The solution seems reasonable; Chase did take longer than Karenna to solve the problem.

Step 5: Communicate the solution
- Chase took 18.17 minutes to solve the problem.

Therefore, Chase took 18.17 minutes to solve the problem.

To use the five-step thinking plan to solve this problem:

Step 1: Understand the problem
- Wallpaper for the walls costs $18 per roll.
- Wallpaper for the border costs $11 per roll.
- The room requires 14 rolls of wallpaper for the walls and 8 rolls for the border.
- We need to find the total cost for the decorating job.

Step 2: Make a plan
- We'll calculate the cost of wallpaper for the walls and the cost of wallpaper for the border separately.
- Then, we'll add the two costs together to get the total cost.

Step 3: Solve the problem
- Cost of wallpaper for the walls: 14 rolls * $18 per roll = $252
- Cost of wallpaper for the border: 8 rolls * $11 per roll = $88
- Total cost: $252 + $88 = $340

Step 4: Check the solution
- The solution seems reasonable; the total cost should be the sum of the costs for the walls and the border.

Step 5: Communicate the solution
- The total cost for the decorating job is $340.

Therefore, the total cost for the decorating job is $340.
