Natalie has 300 cookies for a bake sale. She makes 8 more batches with 12 cookies in each batch. She sells 6 bags of cookies with 21 cookies in each bag. Natalie says she has about 100 cookies left to sell.

Is Natalie’s estimate reasonable?

no her answer is incorrect.

300 [ beginning]

made 96 more [ 8×12 ( this is for the 8 bathces she made ,with 21 in each batch)]

sold 126 [ 6×21 ( six bags with 21 each)]

therefore, ( 300+96)-126=270

she still has 270 more cookies to sell

-hope this helps
