Answer 1

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

1. Calculate the total revenue from selling the cookies: \[ \text{Revenue} = \text{Price per batch} \times \text{Number of batches sold} = 15 \times x \] Plugging in \(x = 10\): \[ \text{Revenue} = 15 \times 10 = 150 \]

2. Subtract the expenses: Maria has already spent $20 on baking supplies, so we subtract this cost from the revenue: \[ \text{Total Money Made} = \text{Revenue} - \text{Expenses} = 150 - 20 = 130 \]

Therefore, if Maria sells 10 batches of cookies, she will make a total of $130.

Answer: $130
