To calculate the total amount of money Maria will make from selling the cookies, you can use the equation:
\[ y = 15x \]
where \( y \) is the total money made and \( x \) is the number of batches sold.
If Maria sells 10 batches of cookies, we can substitute \( x = 10 \) into the equation:
\[ y = 15(10) = 150 \]
So, Maria will make $150 from selling 10 batches of cookies.
However, since she has already spent $20 on baking supplies, the profit she will actually keep would be:
Profit = Total money made - Cost
Profit = $150 - $20 = $130.
So, while she makes $150 from sales, her net earnings after covering her expenses will be $130.
Therefore, the correct response is \( 130 \).
\[ y = 15x \]
