Introduction

In this problem, we are given that Lucy plants 29 flowers in 2 hours. We need to find the equation that represents the number of flowers, ${$ y $}$, Lucy plants in ${$ x $}$ hours, assuming she plants flowers at a constant rate.

Constant Rate of Flower Planting

When we say that Lucy plants flowers at a constant rate, it means that she plants the same number of flowers in a given time period. In this case, she plants 29 flowers in 2 hours. To find the rate at which she plants flowers, we can divide the number of flowers by the time taken:

Rate of Flower Planting

Rate = Number of flowers / Time taken = 29 flowers / 2 hours = 14.5 flowers per hour

Equation Representing the Number of Flowers

Now that we know the rate at which Lucy plants flowers, we can write an equation to represent the number of flowers she plants in ${$ x $}$ hours. The equation will be in the form:

y = rate × time = 14.5 flowers per hour × ${$ x $}$ hours = 14.5x

Simplifying the Equation

We can simplify the equation by multiplying 14.5 by ${$ x $}$:

y = 14.5x

Conclusion

Therefore, the equation that represents the number of flowers, ${$ y $}$, Lucy plants in ${$ x $}$ hours is:

y = 14.5x

This equation shows that the number of flowers Lucy plants is directly proportional to the time she spends planting.

Answer

The correct answer is:

C. ${$ y = 14.5x $}$

Explanation

The other options are incorrect because they do not accurately represent the rate at which Lucy plants flowers. Option A is incorrect because it divides 20 by 2, which is not the rate at which Lucy plants flowers. Option B is incorrect because it does not take into account the time taken to plant the flowers.

Example Use Case

Suppose we want to find the number of flowers Lucy plants in 4 hours. We can plug in x = 4 into the equation:

y = 14.5x = 14.5(4) = 58 flowers

Introduction

In our previous article, we explored the problem of Lucy planting 29 flowers in 2 hours and found the equation that represents the number of flowers she plants in ${$ x $}$ hours. In this article, we will answer some frequently asked questions related to this problem.

Q: What is the rate at which Lucy plants flowers?

A: The rate at which Lucy plants flowers is 14.5 flowers per hour.

Q: How do I find the number of flowers Lucy plants in a given time period?

A: To find the number of flowers Lucy plants in a given time period, you can use the equation:

y = 14.5x

where y is the number of flowers and x is the time in hours.

Q: What if I want to find the time it takes for Lucy to plant a certain number of flowers?

A: To find the time it takes for Lucy to plant a certain number of flowers, you can rearrange the equation to solve for x:

x = y / 14.5

Q: Can I use this equation to find the number of flowers Lucy plants in a fraction of an hour?

A: Yes, you can use this equation to find the number of flowers Lucy plants in a fraction of an hour. For example, if you want to find the number of flowers Lucy plants in 1.5 hours, you can plug in x = 1.5 into the equation:

y = 14.5x = 14.5(1.5) = 21.75 flowers

Q: What if I want to find the number of flowers Lucy plants in a negative time period?

A: If you want to find the number of flowers Lucy plants in a negative time period, you can plug in a negative value for x into the equation. However, keep in mind that this will give you a negative number of flowers, which doesn't make sense in this context.

Q: Can I use this equation to find the number of flowers Lucy plants if she plants at a different rate?

A: No, this equation is specific to Lucy's rate of planting flowers, which is 14.5 flowers per hour. If Lucy plants at a different rate, you will need to use a different equation.

Q: What if I want to find the number of flowers Lucy plants if she plants for a certain number of days?

A: To find the number of flowers Lucy plants if she plants for a certain number of days, you will need to convert the number of days to hours and then use the equation:

y = 14.5x

where x is the number of hours.

Conclusion

In this article, we answered some frequently asked questions related to the problem of Lucy planting 29 flowers in 2 hours. We hope this helps you understand the problem and the equation that represents the number of flowers Lucy plants in ${$ x $}$ hours.
