Maria plans to sell each batch of cookies for $15. If she sells 10 batches, the total amount she makes from selling the cookies can be calculated as follows:
\[
y = 15 \times x
\]
Substituting \(x = 10\):
\[
y = 15 \times 10 = 150
\]
So, if Maria sells 10 batches of cookies, she will make **$150**.
The correct response is:
**$150**
\[
y = 15 \times x
\]
Substituting \(x = 10\):
\[
y = 15 \times 10 = 150
\]
So, if Maria sells 10 batches of cookies, she will make **$150**.
The correct response is:
**$150**
