Final answer:
To find the total number of flowers in Tina's arrangement, we solve the equation 0.60 * T = 15, where T represents the total number of flowers. Dividing 15 by 0.60 gives us 25, so Tina can expect 25 total flowers in her floral arrangement.
Step-by-step explanation:
The student's question involves calculating the total number of flowers in a floral arrangement, given the percentage of roses and the actual number of roses. If 60% of the flowers are roses and Tina is told that there are 15 roses in the arrangement, we need to determine the whole number of flowers based on the given percentage (60%).
Here's the step-by-step explanation to find the total number of flowers:
- Understand the percentage: Knowing that roses make up 60% of the arrangement, we can represent this as 0.60 in decimal form.
- Determine the total number of flowers: Since 15 roses represent 60% of the total flowers, we can set up a proportion to find the total number of flowers (T): 0.60 * T = 15
- Solve for T: Divide both sides of the equation by 0.60 to find T. T = 15 / 0.60
- Calculate the total: Perform the division to find T. T = 25
Therefore, Tina should expect 25 total flowers in her floral arrangement.
