Question

Kelly is planting flowers in the backyard. She has already planted 26 flowers, and wants to plant 7 flowers every day. For how many days does she need to plant flowers to plant exactly 54 flowers?
Let d be the number of days Kelly plants flowers for. Start by writing an expression that represents the number of flowers she plants.
Great job!

You got it!
What does your answer of 4 mean in this situation?
7d+26 = 54
d = 4

Kelly needs to plant flowers for 4 days to fill the garden.

Kelly spends $4 on each flower.

Kelly can plant 4 flowers to fill the garden.
Great job!
Let’s say that Kelly wants to plant up to 54 flowers in the garden. Complete the statement to write an inequality that represents Kelly planting up to 54 flowers.
7d+26 = 54
d = 4


7d+26 54

Answer 1

To express that Kelly wants to plant up to 54 flowers, we write an inequality. Since Kelly has already planted 26 flowers and plans to plant 7 flowers each day, we can write the inequality as follows:

\[ 7d + 26 \leq 54 \]

This means that the total number of flowers she has planted (the 26 already planted plus 7 flowers for each day she plants) should be less than or equal to 54.

Now, let's solve the inequality for \( d \):

1. Start with the inequality:
\[ 7d + 26 \leq 54 \]

2. Subtract 26 from both sides:
\[ 7d \leq 54 - 26 \]
\[ 7d \leq 28 \]

3. Divide both sides by 7:
\[ d \leq \frac{28}{7} \]
\[ d \leq 4 \]

So the inequality \( 7d + 26 \leq 54 \) shows that Kelly can plant for up to 4 days to remain at or below the target of 54 flowers.
