Answer 3

Problem Analysis

We are given two flower beds, one with 15 tulips and the other with 20 tulips. We need to determine how many tulips are left on these two flower beds after cutting 17 tulips for a bouquet.

Solution

To solve this problem, we can follow these steps:

1. Calculate the total number of tulips on both flower beds. 2. Subtract the number of tulips cut for the bouquet. 3. Calculate the remaining tulips on each flower bed.

Let's calculate the solution step by step.

Step 1: Calculate the total number of tulips on both flower beds

The first flower bed has 15 tulips, and the second flower bed has 20 tulips. To find the total number of tulips, we add these two numbers together:

Total tulips = 15 + 20

Step 2: Subtract the number of tulips cut for the bouquet

We need to subtract the number of tulips cut for the bouquet, which is 17, from the total number of tulips:

Remaining tulips = Total tulips - 17

Step 3: Calculate the remaining tulips on each flower bed

To find the number of tulips remaining on each flower bed, we can divide the remaining tulips equally between the two flower beds:

Remaining tulips on each flower bed = Remaining tulips / 2

Now, let's calculate the solution.

Calculation

Step 1: Calculate the total number of tulips on both flower beds: Total tulips = 15 + 20 = 35

Step 2: Subtract the number of tulips cut for the bouquet: Remaining tulips = 35 - 17 = 18

Step 3: Calculate the remaining tulips on each flower bed: Remaining tulips on each flower bed = 18 / 2 = 9

Answer

After cutting 17 tulips for the bouquet, there are 9 tulips remaining on each of the two flower beds.

To verify the solution, we can also solve the problem using a different method.

Alternative Solution

We can also solve this problem by subtracting the number of tulips cut for the bouquet directly from each flower bed.

Step 1: Subtract the number of tulips cut for the bouquet from the first flower bed: Remaining tulips on the first flower bed = 15 - 17 = -2

Step 2: Subtract the number of tulips cut for the bouquet from the second flower bed: Remaining tulips on the second flower bed = 20 - 17 = 3

Verification

The alternative solution gives us -2 tulips on the first flower bed and 3 tulips on the second flower bed. However, we cannot have a negative number of tulips, so we need to adjust the solution.

Since we cannot have a negative number of tulips, we can assume that the first flower bed had 0 tulips remaining after cutting 17 tulips for the bouquet. Therefore, the remaining tulips on the second flower bed would be the total remaining tulips minus the 0 tulips on the first flower bed:

Remaining tulips on the second flower bed = Remaining tulips - 0 = 18 - 0 = 18

So, the alternative solution also confirms that there are 9 tulips remaining on each of the two flower beds.

Both methods provide the same result, confirming that there are 9 tulips remaining on each of the two flower beds.
