Bot GPT 4-o mini To find the correct equation that represents the relationship between the number of cookies sold (c) and the amount of money earned (a), we need to take into account both the revenue from selling cookies and the initial cost of supplies.
- Each cookie is sold for $2, which means if they sell \( c \) cookies, the amount earned from selling cookies is \( 2c \).
- The total amount earned, \( a \), is the revenue minus the initial cost of supplies.
Since the club spent $40 on supplies, the equation should express the amount of money earned after accounting for that cost. Therefore, the correct equation should look like this:
\[ a = 2c - 40 \]
This means that the total amount earned (\( a \)) is equal to the revenue from selling cookies (\( 2c \)) minus the initial cost of supplies ($40).
So, the answer is:
a = 2c - 40
