Answer 1

To find out how much money Maria will make when she sells 10 batches of cookies, you can use the following steps:

1. Calculate the total revenue from selling 10 batches of cookies. Since each batch sells for $15, the total revenue \( y \) from selling \( x = 10 \) batches is: \[ y = 15 \times x \] \[ y = 15 \times 10 = 150 \]

2. Next, we need to consider the $20 she spent on baking supplies. To find the net amount of money Maria makes, we subtract her expenses from the total revenue: \[ \text{Net amount} = y - \text{expenses} \] \[ \text{Net amount} = 150 - 20 = 130 \]

Therefore, if Maria sells 10 batches of cookies, the total amount of money she will make after covering her expenses is $130.

So the answer is $130.
