Answer 1

To find out how much money Maria will make from selling 10 batches of cookies, we can use the following steps:

1. Calculate the total income from selling the cookies: \[ \text{Income} = \text{Price per batch} \times \text{Number of batches sold} = 15 \times 10 = 150. \]

2. Since Maria has already spent $20 on baking supplies, we need to subtract this expense from the total income to find the net money she makes: \[ \text{Total money made} = \text{Income} - \text{Expenses} = 150 - 20 = 130. \]

So, if Maria sells 10 batches of cookies, she will make a total of $130 after covering her expenses.

The correct response is: $130.
