Monica made 350 cookies for the bake sale. She sold them for $0.65 each. She sold of the cookies.



How much money did Monica collect?

Answer 1

A.

Answer: $172.00.

Answer: $182.00.

Explanation: If she sold all of the cookies, she would have collected $227.50. Because she only sold of the cookies, she collected less than $227.50.
