Question
The sports boosters club is having a bake sale to buy uniforms. They want to raise $250. They need to rent a booth for $20. How many dozen cookies will they need to sell if they charge $3 per dozen?
Which equation could be used to solve this problem?
250 = 3 - 20 c
250 = 20 - 3 c
250 = 20 c - 3
250 = 3 c - 20
Which equation could be used to solve this problem?
250 = 3 - 20 c
250 = 20 - 3 c
250 = 20 c - 3
250 = 3 c - 20

To determine how many dozen cookies the sports boosters club needs to sell to cover the booth rental and achieve their fundraising goal, we can break down the costs.
1. They want to raise a total of $250.
2. They will spend $20 on renting the booth.
3. The revenue from selling cookies will be $3 per dozen.
Let \( c \) represent the number of dozen cookies sold. The total revenue from selling \( c \) dozen cookies is \( 3c \).
The equation that represents the situation is:
\[
\text{Total Revenue} - \text{Cost} = \text{Amount to Raise}
\]
This can be written as:
\[
3c - 20 = 250
\]
Rearranging this gives the equation that correctly reflects the problem:
\[
250 = 3c - 20
\]
Thus, the correct equation from the options provided is:
**250 = 3c - 20**
