Melissa baked 8 trays of 5 cookies each. She sold 3 plates of cookies. Which expression correctly represents how many cookies she sold? Circle the best answer.Here are the answer to choose, i don't know how to get the answer?
A.(83)*12
B.3*12
C.8*12

The 8 has nothing to do with it.
She sold 3 plates of 5 cookies each,
3*5
so none of the above. Do you have a typo?
